摘要

Phase precipitation and mechanical properties of TC21 titanium alloy with two different initial microstructures during heat treatment were determined. Result indicated that compared with coarse microstructure alloy, fine microstructure alloy developed finer microstructure, more unstable <em>ω</em> and <em>α</em>₂ precipitates with much smaller size and lower volume fraction, and obtained better mechanical properties during heat treatment.
