It is found that the total drop of electrical resistance in the crystallization process is 10—20% generally, but the metallic glasses Pd-Fe-Si seemed to be something special and their electrical resistance was measured to be directly related to their Fe content. The electrical resistance of the metallic glasses Pd_(0.78)Fe_(0.05)Si_(0.17) increases during isothermal crystallization, yet the reason is not clear. From the viewpoint of kinetics, an addition of Fe, Co or Ni into Pd-Si system may increase their crystallization activation energy and decrease their crystallization mode coefficient, thus, makes them more stable owing to retarding the nucleation. It is believed that the stability of metallic glasses would be considered by both thermodynamic and kinetic basises other than the crystallization temperature. 收稿日期: 1986-01-18      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 周新铭 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1986/V22/I1/99 1 Scott, M.G.; Ramachandrarao, P., Mater.
