To determine the effect of γ\ ightleftharpoonsα transformation due to cold working upon the characteristics of a ferromagnetic γ-phase alloy, the thermal expansion, Young’s modulus and its temperature coefficient were measured on alloy specimens containing 27% of Co, 9% of Cr, 17% of Ni, and the rest Fe which were subjected to cold rolling to various reductions. It was found that the above characteristics were changed very much, showing anomalies caused by cold rolling. With subsequent heat treatment at various temperatures, anomalous changes of the characteristics occured at temperatures from 550° to 600°C, and recrystallization began at 700°C, resulting in a decrease of the anomalies. By observation of the microscopic structure and hardness tests, it was confirmed that the characteristics of the alloy were affected by the γ-α transformation due to cold working.
