摘      要：Compression tests were performed at room temperature to investigate the effects of hydrogenation temperature on compressive properties of Ti6 Al4 V alloy treated by continuous multistep hydrogenation treatment(CMHT).Pressure-composition isotherms and micro structures were also *** showed that the equilibrium hydrogen pressure increased,and the hydrogen absorption rate decreased with the increase of hydrogenation *** amounts ofβphase andαmartensite increased first and then decreased when Ti6 Al4 V alloy was treated by four times CMHT with the increase of hydrogenation *** temperature played a different role on the compressive properties of CMHT-treated Ti6 Al4 V *** ultimate compression of Ti6 Al4 V alloy treated by 11 times CMHT at850℃increased by 83.3%as compared to the as-received Ti6 Al4 V *** compressive properties of Ti6 Al4 V alloy were dependent on the amounts of different phases and microstructures when Ti6 Al4 V alloy was treated by CMHT at different temperatures.
