| Abstract: | In situ synthesis, microstructures, and properties of 10 vol.% TiC and (Ti,W)C-reinforced Fe-Mn-Al austenitic steel matrix composites have been reported in this paper. The microstructure of the prepared samples has been characterized by using scanning electron microscopy and X-ray diffraction technique. The abrasion wear resistance and mechanical properties such as hardness and impact energy of both the composites as well as the unreinforced Fe-Mn-Al austenitic steel have been evaluated. The (Ti,W)C-reinforced composite has higher impact energy and slightly lower hardness values compared to that of TiC-reinforced composite. The TiC-reinforced composite exhibits the best abrasive wear resistance of all the materials tested. |
