Abstract

Fig. 6 depicts the structural effects of tempering by heating for thirty minutes at 630 cleg. C., followed by cooling off in the furnace subsequent to the hardening treatment shown in No. 4. The reduced hardness is 190 V.P.N. This tempering treatment permits the transformation of the beta into alpha plus delta in such a manner that the hard delta constituent is evenly distributed throughout the mass. Thus a hard constituent is embedded in a soft matrix and this offers an excellent abrasion‐resisting material, together with considerable toughness. Higher magnification would show that the delta has commenced to spherodise, thereby preventing the growth of a lamellar structure, and reducing the possibility of fragility along the delta planes.
