用机械合金化方法由元素粉末制备了Ａｌ１ － ｘ Ｗｘ（ ｘ ＝ ０ ．１ ，０ ．２ ，０ ．５ ，０ ．９） 合金。用Ｘ 射线衍射法对球磨后的粉末进行了分析， 并用扫描电镜和透射电镜观察了形貌并研究了晶相结构。结果表明， 球磨后Ａｌ 在Ｗ 中的固溶度大大扩展， 但球磨到２５０ｈ 该系统仍未形成非晶； Ａｌ０ ．５ Ｗ０ ．５ 粉末经２５０ ｈ球磨后出现一结构为体心四方的新相。热力学计算表明该系统不能形成非晶 Al 1 - x Wx (x = 0.1, 0.2, 0.5, 0.9) alloys were prepared from elemental powders by mechanical alloying. The powder after milling was analyzed by X-ray diffraction. The morphology and crystal structure were observed by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The results show that the solid solubility of Al in W after ball milling greatly expands, but the system has not formed amorphous ball after 250h milling. 5 W0. 5 after 250 h ball milling a structure for the heart of the Quartet’s new phase. Thermodynamic calculations show that the system can not form amorphous
