Investigation on the microstructure evolution and dynamic recrystallization mechanisms of TiAl alloy at elevated temperature

The flow stress–strain curves appear to be sensitive to deformation conditions. The ratio of critical strain to peak strain εc/εp follows a linear relationship except when the temperature is 1240 °C and the strain rate is 0.001 s−1. During the deformation, the fragmentation and decomposition of γ/α2...
