采用熔铸法制备等摩尔比的AlCoCrCuFe高熵合金。利用X射线衍射仪、扫描电镜、能谱分析仪、显微硬度计和摩擦磨损试验机分别测试CeO_2掺杂前后对其物相结构、显微组织和摩擦磨损性能的影响。结果表明:AlCoCrCuFe由 BCC和FCC双相组成,合金中掺杂1%(质量分数)CeO_2后引起衍射峰强度的显著提高。两种合金显微组织均为典型树枝晶,Cu与Ce元素在晶间富集,枝晶内为调幅分解组织。CeO_2的加入使合金显微硬度从441.5HV增加到475.3HV,摩擦因数与质量损失率分别从0.55,1.44%降低到0.4,1.28%。 |

AlCoCrCuFe high-entropy alloy was fabricated by melting-casting method.The phase structure,microstructure and friction and wear property for this alloy without and with CeO_2 doping were investigated by XRD,SEM,EDS,microhardness tester and friction-wear tester,respectively. The results show that AlCoCrCuFe alloy has BCC+FCC dual phase structure.1%(mass fraction) CeO_2 addition improves the diffraction peak of AlCoCrCuFe alloy.The microstructure of two above alloys is typical dendrite structure.The interdendrite region is mainly Cu-rich and Ce-rich area,and the dendrite microstructure is layered grid structure of spinodal decomposition.After CeO_2 adding, the microhardness increases from 441.5HV to 475.3HV,and the friction coefficient and the mass loss rate decrease from 0.55 and 1.44%to 0.4 and 1.28%,respectively. |
