摘要：

Hot compressive experiments of Ti-45Al-7Nb-0.15B-0.4W (mole fraction, %) alloy canned by 45(#) carbon steel were conducted at 1050-1230 degrees C on Gleeble1500 hot simulator with nominal deformation of 30% and strain rate of 0.01 s(-1). The displacement-loading curves were obtained, and the macrostructure and microstructure were observed. The results show that the hot compressive temperature of TiAl alloy must be higher than 1050 degrees C and lower than 1230 degrees C with 45(#) steel can, and its optimum temperature is 1180 degrees C. The highest actual deformation of TiAl alloy canned by 45(#) steel is 50% with nominal deformation of 30%. The grains after being hotly compressed are flattened and elongated.
