英文摘要	The effects of remelting temperature and holding time on microstructural evolution of Mg-7Zn-0.3V magnesium alloy were investigated by semi-solid isothermal heat treatment. The results indicate that the holding temperature and holding time have significant effects on microstructural evolution of the Mg-7Zn-0.3V alloy during isothermal temperature process. By increasing the holding temperature or prolonging the holding time, the non-endritic structures in Mg-7Zn-0.3V can be transformed into smaller and more uniform spherical particles.When the holding temperature is too high or holding time is too long, the semi-solid particles will combine and grow up, the microstructural evolution mechanism is consistent with the rule of Ostwald ripening mechansim. The best parameters of isothermal heat treatment are 605 holding temperature and 40 min holding time, obtaining the semi-solid microstructure with the average partial size of 48.5 µm and the roundness of 1.26. © 2018, Science Press.
