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℃.
