In-situ observation microstructure evolution and growth kinetics of lamellar γ phases in Ti44Al alloy during heat treatment

To study mechanism of microstructure evolution in TiAl based alloys during heat treatment, Ti44Al alloy was heat treated at 1240 °C for 0.5/1.0/2.0/2.5/3.0/5.0/7.0 h before being quenched in water. Chemical composition, phase component and microstructure are characterized by XRF, XRD, OM, SEM and ED...
