In addition to this, the relationship between height of theinternal friction peak and the carbon content in the manganese steel containing 18.5% manganesewas also accurately determined, the obtained curve shows that the intersection of axis indicating thesolubility of carbon for this steel really exist. So that, the internal friction peak induced by the interstitial atoms diffusion in the pure metalof face center cubic crystal was owing to the rotation of the atomic pair of two neighbouring atomsin the crystal lattice under the action of stress. The state of carbon atoms may be modified by ad-dition of alloying elements, it can considerably reduce the possibility of formation of carbon atompair, consequently the internal friction peak in the high manganese alloy steel is primarily due tothe rotation of carbon-manganese atom pair. 收稿日期: 1959-01-18      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 钱知强 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1959/V4/I1/69 [1] Розин,К.М.и Финкельштейн,Б.Н,ДАН СССР 91(1953) ,811． [2] 葛庭燧、王其闵,物理学报 11(1955) ,387． [3] 葛庭燧、钱知强、卡列尔·密歇克,物理学报 11(1955) ,403． [4] 葛庭燧、杨本炜,物理学报 13(1957) ,409． [5] 葛庭燧、钱知强,物理学报 12(1956) ,607． [6] 程开甲、张杏奎,物理学报 14(1958) ,71． [7] 程开甲,物理学报 11(1955) ,163． [8] 工业宁、朱建中,科学通报1957年第17期,页530． [9] Григорьев, А.
