Creep and hardening behavior of 6101 aluminum alloy manufactured by wiredrawing process

Abstract

Purpose

The purpose of this paper is to present the effect of the aging at 200°C on creep and hardening behavior of hardenable 6101 aluminum alloy manufactured by an industrial wiredrawing process used for construction of self-supporting overhead aerial power line conductors.

Design/methodology/approach

The creep tests were carried out under applied constant stress 100 MPa and constant temperature 150°C. Hardness measurements were also used to investigate the mechanical behavior of the aged alloy. Micrographs of the fractured wires by creep tests were performed by scanning electron microscope. Electrical resistivity of the aged alloy was measured at different time of the aging treatment.

Findings

The authors have found the relationship between the precipitation sequence, the mechanical properties and the electrical resistivity of aged 6101 aluminum alloy.

Originality/value

The optimum properties were also deduced.
