Solid State Reaction in Nanocrystalline Ti60Si40 Mixture under High Pressure

Nanocrystalline mixture of Ti60Si40 was prepared by ball milling and the solid state reactions between Ti and Si have been studied under different pressures. The phase composition of the samples were identified by X-ray diffraction and electromicrocopy. The results indicated that the amount of a new phase formed during milling grown up at certain pressure and temperature, while its growth rate decreases with increasing pressure. No reactions occur and only the growth of nanocrystals in the same sample when treated under the same conditions at normal pressure.
