抄録

The authors have been studying on the complicated phase transformations occuring in Cu-Al binary alloys by means of the dilatometric and the electric specific resistance measurements. In this report, the specific-heat measurement was carried out to account for the cause of an alteration in Al concentration which appeared in several heat-treatments, namely, in the case of air-cooling and furnace-cooling from the β phase and in the case of the reversible treatment of the β′ martensite respectively. As a result of the experiments, it was found out that the ordering reaction, Cu3Al, advanced quickly during the above treatments, resulting, in the alteration in Al concentration and Ms point, and the β′ martensite containing the Al concentration close 12.4 wt%, the Cu3Al composition, coming into formation.
