摘要：

Microstructure evolution of Ti14 (alpha+Ti(2)Cu) alloy during semi-solid isothermal process at different temperatures was investigated. The results reveal that both the temperature and holding time have effect on the grain growth behavior. The grains grow obviously and the degree of globularity increases with the increase of holding time. According to the statistic analysis of experimental data, the grain growth indices are 0.88 and 0.97 at 1 000 degrees C and 1 050 degrees C, respectively, which indicates that increasing isothermal temperature would accelerate microstructural evolution.
