Abstract

ABSTRACTThe effect of DO3 transitions on the yield behavior of alloys near the Fe3 Al composition was investigated by tensile tests. Above 400°C, DO3 (Fe3 Al) ordered alloys exhibited an anomalous increase in yield strength with temperature with a peak value around 560 to 600°C which was not observed if the DO3 ordered alloys were also aged before testing. This yield behavior is explained by the precipitation of a (disordered solid solution) and the formation of B2 (FeAl) via the sequential reactions: DO3→α+DO3→α+B2.
