Abstract
Hot compressive experiments of Ti–45Al–7Nb–0.15B–0.4W (mole fraction, %) alloy canned by 45# carbon steel were conducted at 1050–1230 °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 °C and lower than 1230 °C with 45# steel can, and its optimum temperature is 1180 °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.
