Abstract: A nanophase composite powder has been synthesized by ball milling of a mixture of elemental Ti, Al and graphite powder with the composition of Ti₆₅ Al₁₅C₂₀ . The nanophase TiC is distributed as ultrafine particles in an amorphous Ti-Al matrix. The present process combines alloying with solid state reaction, which is controlled by interdiffusion of elements.
