Effect of sintering temperature on microstructure and properties of VC/Fe composite

摘要：

　　VC/Fe composite samples were fabricated by sintering at 1050,1100 and 1150℃ in vacuum.The microstructure and mechanical properties of samples were examined,and the relationship of structure and mechanical properties for VC/Fe composite sintered at different temperature were studied.The results show that fracture toughness,hardness and density is increasing obviously at 1050-1100℃with the increasing sintering temperature,but the growth trend increases slowly at 1100-1150℃; in whole process with temperature increased,Flexure strength heighten trend obviously.The microstructure of VC/Fe composite changed from particles piled up together to the microstructure particles closely,VC particles set gradually into Fe with temperature increased,and the gap reduced gradually.
