Abstract：The structure and crystallization on heating of the amorphous alloy Fe_(100-x)P_xduplicated film made by electrodeposition have been examined by DTA,TEM andX-ray diffraction.The observation on alloy Fe_(86)P_(14)which is approach to the eu-tectic composition of Fe-P system is shown as diffuse scattering ring pattern ofelectron diffraction and broadened peak of X-ray diffraction.The crystallization ofthe Fe_(100-x)P_(14)deposited film seems to be the processes of low temperature relaxa-tion,formation of supersaturated solution of α-Fe(P),precipitation of Fe_3P fromα-Fe(P)as well as formation of stable phases of α-Fe(P)and Fe_3P.The Fe_(86)P_(14)grain growth is initiated above 745℃ with a steady exothermal peak on DTAcurve.The initial temperature of crystallization of Fe_(100-x)P_x amorphous alloy in-creases and of precipitation of Fe_3P decreases with the increase of its P content.The initial crystallization temperature of Fe_(86)P_(14)is about 250℃. 收稿日期: 1985-03-18      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 王晋桓 王汝耀 李先勇 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1985/V21/I3/94 1 上平晓,日本专利,昭52-140403,(1977) . 2 王晋桓;王汝耀;刘泽勤,Fe-P电沉积非晶层的制备工艺,第三届非晶物理及材料学术讨论会论文,1982年. 3 Masumoto,T.;Kimura,H.;Inove,A.,Mater.Sci.Eng.,23(1976) ,141． No related articles found!
