High Energy Ball Mill Process Research of High Temperature Dispersion Strengthened Nickel Pre-alloy Powder
摘要
Abstract
this paper studied on the Al2O3 manufacture of high temperature dispersion strengthened nickel pre-alloy powder which was prepared by mechanical alloying method;through changing the ball milling technique parameter and analyzing the effect on mechanical alloying process caused by ball milling speed ball and material ratio, and also through analyzing the SEM, XRD, the particle size and bulk density test, the best ball grinding process parameters was concluded. The results showed that dispersion strengthened nickel high temperature pre-alloy powder size was decreased with ball milling speeding up;when the ball milling speed was 400rmp and the ball material ratio was 20:1, the higher apparent density and the smaller particle size alloy powder could be realized.关键词
