Abstract
Ti(C,N)/Fe composites samples were fabricated in vacuum and Ti(C,N) content was respectively 20vol.%, 30vol.% and 40vol.%. The relationship of microstructure and mechanical properties for Ti(C,N)/Fe composites with various Ti(C,N) content were studied. The results indicated that the flexural strength and wear resistant increased with increasing the content of Ti(C,N)in the range of 0 to 30vol.%, then decreased with further increase of Ti(C,N) content, and the fracture toughness decreases with increasing Ti(C,N) content integrally, while the Vickers hardness increased with the increase of Ti(C,N) content. The microstructure of Ti(C,N)/Fe composites is uniform, fine grains, and grains combine more closely with Ti(C,N) 30vol.%. By comparing the properties of the material was relatively good with Ti(C,N) 30vol.% at 1300°C.
