The effect of mechanical activation on sintering and mechanical properties of Fe-50Ni-TiC composite

This study deals with the processing, microstructure, and sintering behavior of TiC-reinforced NiFe matrix composites, containing 5, 10, 20 and 30 wt.% TiC. Mechanical alloying and powder technology were used to successfully fabricate the composite. The characteristics of the milled powders and the consolidated specimens were examined using scanning electron microscopy and X-ray diffraction method. The microstructural study revealed that the TiC particles were distributed uniformly in the NiFe matrix phase. The composite hardness also increased with TiC content.
