摘要

TiAl alloy is the current hot-spot material of lightweight high-temperature structure in aerospace engineering, of which the final microstructure is largely determined by its cooling process. Due to the complexity of the phase diagram and phase transition of TiAl alloys, it has become an important issue to obtain a fine-grained structure by controlling the cooling process for engineering research.The results of cooling transformation of TiAl alloy were reviewed, and the progress in Ti-48Al-4Nb-2Cr alloy was presented including expounding the solidification path and phase transformation behavior of TiAl alloy firstly, then the continuous cooling transformation (CCT) and isothermal cooling transformation (TTT) behaviors. Furthermore, a CCT diagram of Ti-48Al-4Nb-2Cr alloy was established and a fine-grained NL (FGNL) microstructure was obtained.
