摘要
The influence of hydrogen on the superplasticity and microstructure in a TidAl-4V alloy has been investigated. The addition of a small amount of hydrogen into the alloy improves the superplasticity, decreases the dislocation density and promotes the flow of beta phase along the alpha-alpha grain boundaries. The correlations of the optimum superplasticity with the microstructural factors were discussed.
