In this study investigated production TiC-NiAl and TiC-Ni3Al composites with a combustion synthesis technique. Ti2Ni , Al , Ni and carbon powders were used as the starting materials. X-Ray diffraction (XRD) method was used to characterize the reaction products and scanning electron microscopy (SEM) analysis was used to study the microstructure of the composites. The results show that production of the TiC-NiAl & TiC-Ni3Al composites is feasible by the combustion synthesis. XRD analysis shows that NiAl and Ni3Al can be formed at different ratio of Ni. Al. Also the results of the micro hardness testing for the mentioned composites indicates that with increase in the combustion temperature and the C/Ti ratio in the TiCx compound, the hardness will increase.
