In this investigation, TiN / TiB 2/ TiAl nano-composite powder was produced by mechanical alloying technique and subsequent heat treatment. A powder mixture of Ti , BN , and Al with a molar ratio of 4:2:1 was milled for up to 70 h. Microstructures were studied and characterized using X-ray diffraction, scanning electron microscopy and energy-dispersive spectroscopy. The results indicated that TiN and TiB 2-based phases were formed in an amorphous Ti ( Al ) matrix after 30 h of ball milling. With progression of the milling, the amorphous Ti ( Al ) solid solution is partially crystallized and the particle size reduced significantly. Subsequent annealing of the milled product at 600 °C for 0.5 h resulted in the transformation of the unstable amorphous Ti ( Al ) to TiAl crystal structure and formation of TiN / TiB 2/ TiAl nano-composite powder.
