| 摘 要： | 在Ｃｕ－Ｗ系中，用机械合金化的方法能得到过饱和固溶体，而该系在液、固相状态下完全不互溶，这说明由于机械球磨引起的粒子细化对扩展固溶起了决定性的作用．用Ｘ射线衍射、扫描电镜（ＳＥＭ）、透射电镜（ＴＥＭ）测试了该固溶体的结构，其稳定性用ＤＴＡ热分析测定．

| Abstract: | CU-W supersaturated solid solutions were prepared by mechanical alloying, whereas such a binary system is known to be immiScible in solid and liquid state.This suggeSts that the particle refinement due to mechanical pulverization may play a critical role on the extension of solubility. The structure and steady of samples have been investigated by means of X-ray diffraction,scanning electron microscopy (SEM), transmission electron microscopy (TEM) and differential thermal analysis (OTA) resrectivly. |
