The adding of process - control agent can effectively keep the powder from sticking to the milling ball and the inner wall of containers . the increase of rotating velocity and the ratio of ball to powder can accelerate the phase transformation and thus shorten the alloying time 加入过程控制剂，可以有效地防止粉末粘覆磨球和罐内壁；球磨转速的提高和球粉比的增加，都会加速相转变过程，从而缩短合金化时间。
