Mechanically induced instability in Fe ₂Ti and mechanical alloying of Fe and Ti

Mechanical alloying of Fe and Ti and mechanically induced instability in Fe ₂Ti powders were discussed. It was found that the intermetallic Fe ₂Ti phase was unstable upon mechanical milling producing a mixture of supersaturated α-Fe(Ti) solid solution and FeTi intermetallic phase. It was also found that the mechanical alloying of 2Fe:1Ti leads to the same intermediate and end products. The result show that Fe ₂Ti cannot be obtained through a mechanical alloying process.
