【摘要】 用电沉积法获得Fe-P非晶复层.用差热分析仪、透射电子显微镜及X射线衍射仪研究它的结构和加热晶化过程.Fe₈₆P₁₄含磷量接近Pe-P共晶成分,具有漫散环的电子衍射花样和宽化的X射线衍射蜂.Fe-P沉积层的晶化包括低温弛豫、形成过饱和固溶体.α-Fe（P）,Fe₃P由α-Fe（P）脱溶及形成稳定相.α-Fe（P）和Fe₃P等几个过程.温度超过745℃,Fe₈₆P₁₄进入晶粒长大阶段,出现平缓的放热峰.Fe-P非晶合金晶化开始温度随磷量增加而升高,Fe₃P开始析出温度则下降.Fe₈₆P₁₄开始晶化温度约在250℃.更多还原

【Abstract】 The structure and crystallization on heating of the amorphous alloy Fe_100-xP_xduplicated film made by electrodeposition have been examined by DTA,TEM andX-ray diffraction.The observation on alloy Fe₈₆P₁₄which 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-xP₁₄deposited film seems to be the processes of low temperature relaxa-tion,formation of supersaturated solution of α-Fe（P）,precipitation of Fe₃P fromα-Fe（P）as well as formation of stable phases of α-Fe（P）and Fe₃P.The Fe₈₆P₁₄grain growth is initiated above 745℃ with a steady exothermal peak on DTAcurve.The initial temperature of crystallization of Fe_100-xP_x amorphous alloy in-creases and of precipitation of Fe₃P decreases with the increase of its P content.The initial crystallization temperature of Fe₈₆P₁₄is about 250℃.更多还原
