纳米晶W－Cu固溶体机械合金化研究

SYNTHESIZE OF NANOCRYSTALLINE W Cu SOLID SOLUTION BY MECHANICAL ALLOYING

作者利用机械合金化制备了ＷｘＣｕ（１００－ｘ）（ｘ＝０～１００）合金．当ｘ＞８０时，获得的Ｗ－Ｃｕ合金是一种完全的Ｗ（Ｃｕ）固溶体．实验结果表明，球磨７０ｈ后。

By MA have been synthesized W x Cu (100- x ) ( x =0￣100) alloys. When x >80, the alloy is a total solid solution. The results show that the grain size of the solid solution by milling 70 h is about 10 nm.
