Amorphous binary Cu-Ti and Ni-Ti powders could be produced by mechanical alloying of elemen- tal powders in a high-energy ball mill, and the process parameters used were presented. X-ray diffrac- tion (XRD) was used to follow the progress of the mechanical alloying. The crystallization behavior of amorphous powders was measured by XRD at high temperature up to 800℃ and differential ther- mal calorimetry (DTA). It was found that the ball-to-powder weight ratio should be limited and 10: 1 was favourable in this study, and that a small part of layered crystalline phase which might be re- maining during processing was possible to be transformed to amorphous phase by subsequent heat treat- ment below crystallization temperature T_x, and the T_x of Cu_(43)Ti_(57) and Ni_(45)Ti_(55) amorphous powders were about 450℃ and 500℃ respectively. The free energy curves of the metastable and equilibrim phases at 300℃ for binary Cu-Ti system were calculated and a schematic illustration based on the mode of diffusion couples was proposed to explain the amorphization process produced during milling.

采用机械合金化方法将元素粉末制成Ni_(50)Ti_(50)非晶合金。X射线衍射用来跟踪非晶化进程,差热分析用来测定非晶的晶化结晶温度。实验结果表明,当采用15∶1的球料比和1.7~2.8m/s的研磨速度时能够获得典型的X射线衍射谱线。杂质铁每小时平均增加速率约为0.03%。差热分析测得的晶化结晶温度为530℃左右,但当加热时间为1h时,晶化结晶温度降至428℃左右,说明等温退火明显降低非晶的稳定性。
