Based on the chemical compositions,microstructure and mechanical properties of new titanium-alloy Ti-3Al-2Mo-2Zr(TA24),the properties at typical high temperatures of the alloy were investigated.The test plates of the alloy were welded by GTAW,and the postweld heat treatment was carried out at specified temperatures after the nondestructive testing for the welding points.Then,the samples were prepared for mechanical properties and metallographical analyses,aiming at investigating the welding performances and the variations of joint properties at different postweld heat treatment temperatures for the new titanium alloy.The results show that the new alloy has well welding and high temperature resistant performances,and a favorable postweld heat treatment temperature ranging from 650℃ to 750℃ can be determined for the new alloy.
