Effect of Near β Heat Treatment Process on Microstructure of TC18 Alloy

Abstract:

The effects of near β 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 β heat treatment, and the size of α_p does not significantly, but dispersible α_s increases and has a tendency to merge, and then it would not grow up anymore ; β 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.
