Abstract
The solubility of hydrogen in Ti-60 alloy obeys the Sivert's Law and the Arrhenius relationship. The heat of dissolution of hydrogen in this alloy is found to be 42.3 kJ/mol. The experimental results also show that the α + β → β transformation temperature and high temperature yield strength of Ti-60 alloy are continuously decreased with increasing hydrogen contents. The minimum yield strength of the alloy at high temperature occurs at the hydrogen concentration corresponding to the α + β → β transition and further increase in yield strength is due to the hardening effect of hydrogen addition on the β phase. Tensile at 900 °C will make the yield strength reduce about 70% for the alloy containing 0.3% of hydrogen.
