AbstractThe phase transformation behavior of Ti-42Al-5Mn (at.%) alloy from different phase regions with various cooling rates was investigated based on electron probe micro analyzer-backscattered electrons (EPMA-BSE). It is shown that (2) takes place when this alloy is cooled at a high rate, such as water quenching (WQ), oil cooling (OC), from single phase. With the decreasing cooling rate to air cooling (AC), (2) is restrained and is promoted by forming platelets. The room-temperature microstructure is (o) + (2) when alloy cooled (WQ and OC) from ( + ) dual-phase. However, under AC, occurs and platelets form. It should be noted that (2) happens when this alloy cooled from 1180 degrees C (>T-eut) by OC and AC, forming an incomplete lamellae ((2)/) structure in the (2) phase. However, when the alloy cooled from 1100 degrees C (
