摘要
利用机械合金化方法制备Si-Ti合金时 ,发现样品经历了一个固溶→非晶→晶化的过程 ;X射线衍射表明 ,晶化后的样品为首次发现的新相 ;利用计算机进行理论模拟 ,确认这个新相是具有立方结构的金属间化合物SiTi3,给出了其结构示意图 ;对SiTi3的相演变过程及反应机制进行了探讨 .
Si-Ti alloy was prepared by mechanical alloying.The specimen experienced a solid-solution→amorphous→crystallization process.XRD indicated that a new phase was formed for the first time after crystallization.The analysis shows the new phase is intermetallic compound SiTi 3 with cubic configuration.The configuration schematic was given in the paper.The phase transformation and action mechanism of SiTi 3 are discussed.
