Metallic and its compound powder - determination of specific surface and particle size by air permeating method 金属及其化合物粉末比表面积和粒度测定空气透过法
It was found that the mo - cu compound powder after high energy ball milling was in a inequilibrium energy storage state 本文通过对mo - cu复合粉末的机械合金化研究表明,经过高能球磨后的mo - cu复合粉末,处于非平衡储能状态。
The x - ray diffraction analysis of the compound powder showed that the value of the diffraction peak reduced , the breadth of the diffraction peak broadened . there was incrystallizing to a certainty degree of the compound powder 粉末的x - ray衍射分析表明,粉末的衍射峰峰值降低,峰增宽,粉末体系产生了一定程度的非晶化。
The dta showed there was large amount additional energy deposited in the compound powder . by calculation , the 4 - hour milled powder stored 28 . 1 % of phase transformation energy of cu , and the 8 - hour milled powder stored 31 . 4 % 经过计算得出, 4小时球磨粉储能约为cu相变潜热的28 . 1 , 8小时球磨粉储能约为cu相变潜热的31 . 4 。
