Columnar grains formation and mechanical properties improvement of Ti44Al alloy by cyclic directional heat treatment
Ti44Al alloys were conducted cyclic directional heat treatment (DHT) for 1, 4 and 6 cycles at 1750 K to obtain directional microstructure and research their microstructure evolution. Microstructure was observed and mechanical properties was tested. Results show that grains of all treated Ti44Al allo...
