The expansion along the longitudinal direction isless than that along the transverse direction. The cooling rate, the temperature of meltbefore jet casting and the cycling temperature affect the thermal expansion coeffi-cients and anisotropy. The anisotropy of thermal expansion originates from the direc-tional atomic interaction force, atomic oscillatory frequency and the directional shortrange order structure or defects in the alloy Key words： amorphous Fe_(78)B_(13)Si_9 alloy    thermal expansion anisotropy 收稿日期: 1989-03-18      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 陆坚 王景唐 丁炳哲 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1989/V25/I3/102 1 Kraus L, Tomas I, Kratochvilova E, Springmann B, Muller E.
