英文摘要	The volume fraction of primary alpha-phase, the (alpha+beta)->beta transformation temperature and high temperature yield strength of Ti-60 alloy are continuously decreased with increasing hydrogen content in the alloy. The minimum yield strength of the alloy at high temperature occurs at the hydrogen concentration corresponding to the (alpha+beta)->beta transition and then increases due to the hardening effect of hydrogen addition on the beta-phase. The relationship between hydrogen concentration and transformation temperature can be expressed as: t((alpha+beta)->beta)(degrees C)=815+210exp(-3(H)). Tensile at 900 degrees C will make the yield strength reduce about 70% for the alloy containing 0.3% hydrogen.
