借助扫描电镜研究了热处理工艺对金属粉末注射成型晶粒尺寸的影响。结果表明:磁性热处理的加温温度越高,保温时间越长,晶粒越容易长大,晶粒尺寸越大。
The effect of heat treatment process on the grain size of metal powder injection molding was studied by SEM. The results show that the higher the heating temperature of magnetic heat treatment, the longer the holding time, the easier the grains grow and the larger the grain size.
