采用粉末冶金法制备了TiC/Cu复合材料,研究不同TiC含量对TiC/Cu复合材料组织与拉伸性能的影响,并利用扫描电镜、金相显微镜等对样品的表面形貌和拉伸断口形貌进行分析。结果表明,TiC与基体结合紧密且在基体中分布均匀;随着增强相TiC含量的增加,TiC/Cu复合材料的抗拉强度先增大后降低;TiC的加入明显阻碍了基体晶粒长大;当TiC质量分数为2%时,强化效果较好,TiC/Cu复合材料的塑性较好。
TiC / Cu composites were prepared by powder metallurgy. The effects of different TiC contents on the microstructure and tensile properties of TiC / Cu composites were investigated. The surface morphology and tensile fracture appearance of TiC / Cu composites were characterized by scanning electron microscopy Appearance analysis. The results show that TiC is tightly bound to the matrix and uniformly distributed in the matrix. With the increase of the content of TiC, the tensile strength of TiC / Cu composites first increases and then decreases. The addition of TiC significantly hinders the growth of matrix grains When the content of TiC is 2%, the strengthening effect is better, and the plasticity of TiC / Cu composites is better.
