Theheight of the peak was found to increase with the content of δ-ferrite in the specimens.The peak disappeared after the δ-ferrite all decomposed. This indicates that, this peakis associated with the presence of δ-ferrite in the specimen. The activation energy asso-ciated with this peak was measured to be 95,000 (±5,000) calories per mole by themethod of changing frequency. It is suggested that the internal friction peak is a bulkeffect of δ-ferrite in the specimen, and it may be induced by some diffusion process inδ-ferrite. 收稿日期: 1965-02-18      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 孔庆平 刘少谷 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1965/V8/I2/228 [1] 庄育智、李有柯:物理学报,1954,10,321． [2] 庄有智、刘嘉乐:金属学报,1956,1,337． [3] Ting-sui Ke(葛庭燧),Phys.Rev,1947,71,533． [4] Панченко,Е.В.等著,孙一唐译:金相实验室,(冶金工业出版社,1960年),456页.
