The dynamic viscosity and the activation energy of dynamic viscous flow in their rapid flow region have been evaluated. The results showed that the maximum flow rate and the lower viscosity at 30-35℃ above T_g are presented in the Pd-Si base metallic glasses with an addition of third metal Cu, Ag or Ni. The dynamic viscosity of eutectic Pd_(82)Si_(18) at a close level of temperature,10—20℃ above T_g, is obviously lower that of another two binary metallic glasses. On the basis of the free volume model and the entropy model for the viscous flow, the proposal would be made of that the viscous flow behaviour of the metallic glasses is related to their thermal stability and degree of short-range order. 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 郑福前 廖宗尧 胡健松 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1986/V22/I1/107 1 Spaepen, F., Acta Metall., 25 (1977) , 407． 2 Argon, A.S., Acta Metall., 27 (1979) , 47． 3 Taub, A.I.; Luborsky, F.E., Acta Metall., 29 (1981) , 1939． 4 Taub, A.I.; Luborsky, F.E., Mater.
