英文摘要	采用热压烧结方法制备以三元层状碳化物陶瓷Cr2AlC为增强相的Cu-Cr2AlC复合材料.利用X射线衍射(Xrd)和光学显微镜研究复合材料的物相组成和组织形貌;利用维氏硬度仪和万能试验机测试其维氏硬度和抗拉力学性能;利用扫描电镜观察样品拉伸断口形貌.结果表明,当Cr2AlC的体积分数为20%时增强效果最佳,屈服强度和抗拉强度分别达到230和315MPA;Cu基体晶粒细化及增强颗粒与基体之间良好的界面结合是材料强化的主要原因.; Cu-Cr2 AlC composites reinforced by layered ternary carbide Cr2 AlC ceramic were fabricated by hot pressing method.The phase composition,microstructures of the synthesized composites were characterized by X-ray diffraction(XRD)and optical microscope.The Vickers hardness and tensile properties were tested by the Vickers and universal testing machine.The results indicate that the Vickers hardness,yield strength and tensile strength were enhanced significantly by Cr2 AlC particles.The composites′yield strength and tensile strength reach up to 230 MPa and 315 MPa,with the optimum volume fraction of 20%.The grain refinement of Cu matrix and an excellent interfacial bonding between the reinforcement and the matrix contribute to the strengthening.
