The amorphization process wasexamined by X-ray analysis and Mossbauer spectroscopy, and the thermal behavi-our was studied by DSC. The results show that the rate of amorphization is con-trolled by the diffusion reaction at the interfaces and changes with the milling time.The effect of milling conditions on amorphization by mechanical alloying was alsoinvestigated. Key words： mechanical alloying    amorphization    Al-Fe amorphous alloy    Mossbauer spectrum analysis 收稿日期: 1990-05-18      基金资助:国家自然科学基金 服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 汪卫华 肖克勤 储昭琴 董远达 王根苗 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1990/V26/I5/97 1 Johnson W L.
