摘要

As for a two phase TiAl-based alloy, γ/α₂ lamellar structure has been studied, where, various atomic microstructures for interfaces generated by phase transformation and recrystallization upon high-temperature compression have been studied. As expected, mixed interfaces including phase boundary (PB), true twin (TT), pseudo-twin (PT), 120° rotational boundary (RB) and large angle grain boundary (LAGB) can be observed in the as-formed structure. A detailed characterization using high resolution electron microscopy has been performed, which helps to obtaining the optimum microstructure and the corresponding excellent mechanical properties of the TiAl alloy.
