Three separate peaks of the activation energy with varied frequency factors were shown on the spectrum obtained, The frequency factor influences the shape, range, location and continuity of the peak. The Zr content in the Cu-Zr metallic glasses may affect considerably each own structure relaxation spectrum. Their variaty behaviour has also been discussed. 收稿日期: 1984-01-18      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 邓德国 于建 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1984/V20/I1/87 1 Chen, H.S.; Coleman, E., Appl.
