摘要：
The effects of near beta heat treatment on the microstructure of TC18 alloy during three temperature stages were studied. The results show that the microstructure of the sample is tri-modal microstructure after near beta heat treatment, and the size of alpha(p) does not significantly, but dispersible as increases and has a tendency to merge, and then it would not grow up anymore; beta phase would grow up, but the grain boundary has some broken. The experiment result shows that the tri-modal microstructure could obtain high damage tolerance properties of titanium alloy in theory.
