The microstructure of AZ61 magnesium alloy by strain-induced melt activation (SIMA) process was studied to reveal the effects of prior compressive deformation, isothermal temperature and holding time.
研究了AZ61镁合金在应力诱发熔体激活法(SIMA)制备半固态坯料过程中预变形量、等温温度和保温时间对其组织的影响。
During isothermal holding at low temperature, the nonequilibrium segregation promotes precipitation of boron constituent and establishment of equilibrium segregation at grain boundaries.
在较低温度下等温，非平衡偏聚促进了晶界硼相的析出和平衡偏聚的建立。
Grains grow up slowly and are sphericized mainly through elements diffusion with increasing volume fraction of liquid as the increase of the isothermal temperature and holding time.
随着加热温度的升高和保温时间的延长，液相增加，晶粒主要通过原子扩散缓慢长大并发生球化。
The results show that, under the same holding time, grain size and spheroidization increases with the increase of isothermal temperature;
结果表明：当保温时间相同时，随温度的升高，晶粒尺寸和球化程度均增加；
