| Abstract: | Ti-Si 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 was face centered cubic structure. The configuration schematic and the unit cell of Ti3Si were given in the paper. |
