用行星式高能球磨机对成分为Al1-xWx(x =0 .1 ,0 .2 ,0 .5 ,0 .9)的粉末进行了不同时间的研磨 ,用X射线衍射法和电镜对球磨后的粉末的结构和形貌进行了研究 .实验结果表明 ,球磨后Al在W中的固溶度大大扩展 ,可超过 5 0 % (原子分数 ) .用嵌入原子理论和机械合金化扩展固溶度的理论对实验结果进行了分析 ,理论计算结果与实验相符
The powder with the composition of Al1-xWx (x = 0.1, 0.2, 0.5, 0.9) was ground with planetary high-energy ball mill for different time. The effects of ball milling The structure and morphology of the powders were studied.The experimental results show that the solid solubility of Al in W greatly expands to more than 50% (atom fraction) after milling, and the solid solution solubility is broadened by the theory of embedded atoms and mechanical alloying Theoretical analysis of the experimental results, theoretical calculations and experimental results
