Effect of mechanical alloying process for cermet alloy

Mechanical alloying of Titanium, Molybdenum, Nickel and graphite powders was performed using a vibrational ball-mill. Mechanical alloying process of cermet powder was studied by X-ray diffraction, electron probe micro analysis (EPMA) and scanning electron microscopy. Results from X-ray diffraction and EPMA suggested the synthesis of TiC was carried out for about 50 hours and the addition of Ni assisted this synthesis. The difference of mechanical alloying atmosphere had an effect on particle size of TiC after sintered. Mechanical alloyed Ti-C-20mass%Ni-10mass%Mo was able to sinter at low temperature and had a minute structure.
