The purpose of this paper is to study the wear behaviour of eutectic and hypoeutectic Al‐Si‐Mg‐Ce alloys.

Abstract

Purpose

The purpose of this paper is to study the wear behaviour of eutectic and hypoeutectic Al‐Si‐Mg‐Ce alloys.

Design/methodology/approach

The eutectic and hypoeutectic alloys were prepared using permanent mould casting process by varied cerium (Ce) addition in the alloy from 1 to 3 wt%. Dry sliding wear tests were performed against a hardened carbon steel (Fe‐2.3%Cr‐0.9%C) using a pin‐on‐disc configuration with fixed sliding speed of 1 m/s and load 50 N at room temperature of ∼25 degree. Morphologies of both worn surfaces and collected debris were characterised by a scanning electron microscope (SEM) equipped with an energy dispersive X‐ray spectrometer (EDS).

Findings

It was revealed that following the addition of cerium, intermetallic Al4Ce needle‐like structure was present in eutectic alloys whereas CeMg2Si2 blocky phase was present in the hypoeutectic alloys. The increasing of Ce addition up to 3.0 wt% in hypoeutectic alloy led to formation of AlCe3 intermetallic phase. The increase in cerium content up to 2 wt% led to higher wear resistance behaviour for both as‐cast alloys. Formation of craters and localised plastic deformation were observed on the worn surface of both as‐cast alloys, resulting fine particulate and sheet‐like wear debris. The wear resistance was found to be higher for hypoeutectic alloy compared to the eutectic alloy containing Ce.

Originality/value

An attempt has been made to study the influence of intermetallic compound containing Ce in the Al‐Si‐Mg alloys on wear behaviour of both as‐cast alloys.

Abstract

A Cu‐Al bonding system exists when copper wire is bonded onto an aluminum bond pad using thermosonic wire bonding technology. Aged Cu‐Al bonding system was analyzed by measuring the intermetallics layer thickness and its correlation to electrical contact resistance. Result shows that the thickness of Cu‐Al intermetallics layer grows almost linearly to aging time. The activation energy needed for Cu atoms to diffuse into Al was calculated using Fick's law; Q=129.66 kJ/mole and D0=1.628×10−4 m2/s. The calculation of activation energy and impurity diffusity using Model Kidson also shows linear relationship. Electrical resistance of Cu‐Al intermetallics layer was calculated from contact resistance of Cu‐Al bonding system. The result shows that the electrical resistance of Cu‐Al intermetallics layer increases linearly with intermetallics thickness. Its growth rate that was calculated using Model of Braunovic and Alexandrov is double of Model of Murcko.

– This paper aims to investigate the influence of temperature and lignin concentration on the inhibition of carbon steel corrosion in 1 M HCl.

Abstract

Purpose

This paper aims to investigate the influence of temperature and lignin concentration on the inhibition of carbon steel corrosion in 1 M HCl.

Design/methodology/approach

Weight loss corrosion tests were performed at different temperatures in the range of 30-70°C (303-343 K).

Findings

It was found that the corrosion inhibition efficiency (IE) of lignin on the carbon steel decreased when the temperature was increased from 60 to 70°C. However, at lower temperatures ranging from 30 to 50°C, the IE improved, due to occurrence of lignin adsorption on the surface of metal specimens. The IE was higher with increasing lignin concentration, thus reducing the weight loss of the carbon steel. The adsorption phenomenon involved exothermic processes because the value of enthalpy of adsorption (ΔH°ads) < 0 and Gibbs free energy of adsorption (ΔG°ads) were less negative with increase in temperature. The entropy of adsorption (ΔS°ads) had negative values, representing the decrease in disorder of adsorption. The adsorption of lignin on the carbon steel surface in 1 M HCl was comprehensive, as deduced from kinetic and thermodynamic parameters. However, physisorption was the major contributor in the inhibition mechanism. The inhibitive features of carbon steel surfaces showed less damage once the steel was treated in lignin, as evident from macroscopy images.

Practical implications

The use of lignin as an acid corrosion inhibitor at high temperature is practical in metal surface treatment process.

Social implications

The use of organic compounds gives an advantage to the environment, universal health and save cost, as the compounds can be found in nature.

Originality/value

Lignin can act as a flexible corrosion inhibitor within the temperature range of 30-70°C in 1 M HCl because it exhibits comprehensive adsorption (i.e. a combination of both physisorption and chemisorption) at specific concentrations.

Abstract

Purpose

The purpose of this paper is to understand consumers’ willingness to choose Islamic mortgage products as a way to help Islamic banks tap into the Islamic mortgage sector in Malaysia.

Design/methodology/approach

Using the Theory of Interpersonal Behaviour as a point of departure, this study proposes a framework that examines factors influencing consumers’ willingness to choose Islamic mortgage products. A total of 282 usable surveys are obtained from customers of Islamic banks and the data were analysed using partial least squares.

Findings

The results indicate that affect, social factors, and facilitating conditions influence willingness to choose Islamic mortgages. Besides these factors, the added factors, namely, perceived risk and perceived financial benefit, significantly influence consumers’ willingness to choose Islamic mortgages.

Research limitations/implications

This study is confined to two public universities in Malaysia. Further testing of the proposed model across different population groups is necessary to determine the generalisability of this study’s findings. This study applies consumer factors such as affect, social factors, facilitating conditions, perceived risk and perceived financial benefit. Further testing on other factors is needed to expand the findings in this area.

Practical implications

The results could help bank managers make improved decisions about the factors which they need to effectively market Islamic mortgage products. This study provides insights and guidance for bank managers to manage Islamic mortgage products.

Originality/value

The main contribution of this paper is a proposed framework of consumers’ willingness to choose Islamic mortgage products which takes into account the key factors necessary to predict consumers’ demand.

Abstract

Purpose

The purpose of this paper is to investigate the Malaysian homeowners’ intention to participate in the Cash Waqf-Financial Cooperative-Musharakah Mutanaqisah (CWFCMM) home financing model using rigorous scale validation procedures.

Design/methodology/approach

An adapted questionnaire with 26 items was administered to 382 academic and supporting staffs, postgraduate and undergraduate students in three states in Malaysia. The data were analyzed using exploratory factor analysis and confirmatory factor analysis with SPSS 21 and AMOS 21, respectively.

Findings

The results further support the parsimonious nature theory of planned behavior (TPB) with its three original construct of attitude, subjective norm, and perceived behavioral control and an additional construct of perceived cost advantages of the CWFCMM Model. A validated TPB scale with 24 items measured can be proposed to be used as an evaluative tool to assess the level to which the homeowners are interested to participate in the CWFCMM Model.

Research limitations/implications

The modified TPB scale would also facilitate the identifications of factors that influence homeowners’ intention to opt for Islamic home financing (IHF) by non-bank Islamic financial institutions such as financial cooperative.

Practical implications

The CWFCMM Model aims to harness the potential synergy between third-sector economy players such as waqf and financial cooperatives in offering affordable IHF solution to potential homeowners.

Social implications

The CWFCMM Model may enable the Malaysian homeowners to enjoy a more affordable IHF solution, thereby, among others, reducing the purchase and monthly repayment affordability of Malaysians.

Originality/value

There is a dearth of Islamic financial services selection studies, especially within the non-banking, Islamic financial services milieu. The CWFCMM Model, which has been developed by the authors, enriches the limited literature on this subject matter. It will also add value to understand how the customers would react to an alternative IHF provider.

Abstract

Purpose

The purpose of this study is to investigate the effects of service quality, product choice and Islamic debt policy on consumer attitude within the context of Islamic mortgage sector in Malaysia. The present study also examines the effect of attitudinal-behaviour on consumer preference towards preference of Islamic mortgage selection.

Design/methodology/approach

The study is based on questionnaire survey. Data are collected using sample from customers of Islamic banks in Malaysia. The study collects 351 respondents. Data are analysed using partial least squares (PLS).

Findings

The results indicate that service quality, product choice and Islamic debt policy significantly influence consumer attitude, in turn, affecting the Islamic home financing preference. Consumer attitude also mediates the effects of service quality, product choice and Islamic debt policy on the Islamic home financing preference.

Research limitations/implications

Several limitations warrant future research. First, this study considers only a specific user group in one public university. Second, this study does not consider attitude as a moderator. Third, this study suffers from the limited number of factors used. These limitations, however, provide directions for future research.

Practical implications

Our results will add value to the consumer preference topic for Islamic home financing literature. The present study provides bank managers with valuable insights into better planning of Islamic home financing services in Malaysia.

Originality/value

This study is a pioneering effort at exploring consumer attitude and preference from the context of Islamic mortgage sector in Malaysia. The use of PLS analysis provides another important contribution to the literature in this area.

Abstract

Purpose

The purpose of this study is to examine the critical success factors (CSFs) for the receptiveness of Islamic home financing in Malaysia.

Design/methodology/approach

A framework of the CSFs for the receptiveness of Islamic home financing is developed. The framework evaluates the effects of product type, competitive value proposition, Islamic debt collection policy, Islamic bankers' knowledge and maqasid al-Shariah compliance on the receptiveness. Data from 744 usable questionnaires are analysed to confirm the applicability of the framework in Islamic home financing context.

Findings

The results suggest that product type, competitive value proposition, Islamic debt collection policy, Islamic bankers' knowledge and maqasid al-Shariah compliance are significantly related to the receptiveness of Islamic home financing.

Research limitations/implications

Two limitations are available for future studies. Firstly, the respondents of this study are limited to Malaysians, signifying further testing of the proposed model across different geographies is required to determine the generalisability of the model. Secondly, the contributions of the proposed framework are confined to a specific area of Islamic banking products. Thus, extending the framework to other banking products or conducting a comparative study between Islamic home financing and its conventional peer can improve its generalisability.

Practical implications

The results obtained offer a fresh direction on how to market Islamic home financing products successfully, where the new CSFs are brought into play.

Originality/value

This study examines the new proposed CSFs for the receptiveness of Islamic home financing in Malaysia.

Abstract

Purpose

This study aims to examine the impacts of Shariah-compliant products, value-added benefits, mortgage repayment policy and well-versed bankers on the consumer acceptance of Islamic home financing. These variables, thereafter, are called the “critical success factors” (the CSFs) for Islamic home financing.

Design/methodology/approach

Guided by the Islamic theory of consumer behaviour (ITCB), this study intends to propose the specific CSFs that ensure consumer acceptance of Islamic home financing a success. The term success refers to consumers’ willingness to take up the facility. A questionnaire survey was conducted to elicit responses pertinent to the level of agreement/disagreement of the CSFs. A total of 460 respondents usable responses were obtained and analysed accordingly.

Findings

The results obtained indicate that Shariah-compliant products, value-added benefits, mortgage repayment policy and well-versed bankers are instrumental to influence the consumer acceptance of Islamic home financing.

Research limitations/implications

Like other works, this study has confined its context to capture only a limited geographical area, and the study’s contributions are restrained to the variables analysed to a specific context of Islamic home financing in Malaysia.

Practical implications

The results obtained can become as a yardstick to measure the consumer acceptance of Islamic home financing.

Originality/value

New proposed CSFs can help to address the new demand of Islamic home financing accordingly, where a new area of improvement is brought into play. This study also extends the applicability of the ITCB to include Islamic home financing products.

Abstract

Purpose

This research aims to examine and compare differences in waṣiyyah wājibah (obligatory bequest) (WW) practices in Malaysia and Indonesia.

Design/methodology/approach

This is an exploratory qualitative research, employing a thematic analysis approach. Six Muslim Wills (State) Enactments [Enakmen Wasiat Orang Islam (Negeri)] in Malaysia, Islamic Law Compilation (Kompilasi Hukum Islam) in Indonesia, two fatwas (ruling in religious matters) and one court case from each country are analysed. Data is collected from official government websites and other reliable search engines.

Findings

First, the findings show that the WW practice in both countries is similar regarding the quantum of the beneficiaries' entitlement. However, the practice varies between both countries in terms of the types of beneficiaries and how the bequest is distributed. Second, this study shows the potential of WW as an estate planning instrument to complement the existing instruments in each country, especially when addressing family members who are not entitled to succeed by farāʾiḍ (Islamic inheritance law).

Practical implications

The provision of relevant laws and regulations regarding WW needs to be formulated to guarantee the well-being of dependants. The differences in practice between the two countries can be a guideline to expand the WW scope and context to other Muslim countries.

Originality/value

This study is the first attempt to compare WW between two Muslim-majority countries focusing on relevant laws, court cases and regulations.

Abstract

Purpose

Zakat has a strong humanitarian and social-political value. Zakat occupies a central role in Islamic fiscal policy and operations. At the same time, it does not preclude the use of modern tools and techniques in raising the state revenues. Islam provides its own comprehensive approach how the state can raise its revenue and how the revenue should be spend. Zakat is collected from those who are qualified and distributed to the eight recipients as identified in the Quran. Waqf instrument plays an important role in Muslim societies as its support the aged, the poor, the orphans through provision of education, training and business activities. The creation of waqf is strongly advocated, especially the creation of cash waqf in view of the expensiveness of land as waqf. There are collaboration efforts for cash waqf and zakat collection being done through Islamic banks and takaful. The paper aims to discuss these issues.

Design/methodology/approach

The data were source from the inland revenue, government agencies and state religious authorities, interviews, articles and conference reviews, as well as economic reports and later transcribe into charts and figures.

Findings

Its shows the efficiency of wealth distribution according to the Islamic principles and application of the financial inclusion in the Islamic society.

Research limitations/implications

The limitation is in verifying the accuracy of data gathering from the government agencies.

Social implications

The study can be used in financial inclusion through the application of zakah and waqf being applied to alleviate poverty.

Originality/value

The research is an extended work done on zakah and waqf in Islamic wealth distribution.
