摘　　要：在CaCl2熔盐中,以钛精矿为阴极,电解制备了钛铁合金,并对产物进行了XRD和SEM检测。对比不同温度下电解产物的结果表明,温度对扩散合金化过程影响显著,不同温度下电解产物的物相和结构有明显不同。850℃下电解的最终产物是颗粒大小为1μm的TiFe2和Ti离散球型结构,而900℃下电解的最终产物是颗粒大小为3μm的TiFe空间网状结构。In the CaCl2 molten salt,TiFe alloy was prepared by electroanalysis using titanium concentrate as the cathode.XRD and SEM analyses of products were performed.The electrolytic products at different temperatures were compared.Results show that the temperature has significant effects on diffused alloying process,and the phases and structures of electrolytic products are different.At 850 oC,the final electrolytic product is the TiFe2 and Ti discrete ball-type structure with the particle size of 1 μm,while at 900 oC the final product is the TiFe space net structure with the particle size of 3 μm.
