Phase Morphologies and Mechanical Properties during Heat Treatment of a Hotforged near-β Titanium Alloy

摘要：

The effect of heat treatment on the phase morphologies and mechanical properties of a hotforged near-p VT22 titanium alloy has been investigated in detail. The mechanical properties were found to be sensitive to the volume fraction and morphologies of the α phase. Solution treatment (ST) between 750°C and 900°C followed by ice water quenching changed the phase morphology of the primary α phase from lath-like to spherical. Increasing the ST temperature resulted in a decrease in the volume fraction of the alpha phase. This decreased both the strength and ductility. However,the mechanical properties are significantly improved by aging between 500℃ and 600℃.
