Influence of thermohydrogen treatment on microstructural evolution and hardness of Ti600 alloy

Journal Article


Abstract


  • The influence of thermohydrogen treatment (THT) on microstructural evolution and hardness of Ti600 alloy has been studied. The results reveal that there are two types of silicides precipitate in the Ti600 alloy after THT, one is tetragonal silicide S3 (0.357% H, mass fraction), and the other is hexagonal silicide S1 (0.497%). Hydrides (fcc structure) exist in the specimens with 0.357% and 0.497% hydrogen, and hydride 5 tends to be refined with increasing of hydrogen. The hardness of Ti600 alloy increases with increasing of hydrogen, and it is considered that hydride, silicide and lattice defects are the major factors.
