Result indicated that compared with coarse microstructure alloy, fine microstructure alloy developed finer microstructure, more unstable <em>ω</em> and <em>α</em><sub>2</sub> precipitates with much smaller size and lower volume fraction, and obtained better mechanical properties during heat treatment.展开更多
