| 摘 要： | 以Ti3AlC2和Cu粉作为原料,使用放电等离子烧结制备Cu/Ti3AlC2复合材料,研究了不同烧结温度对复合材料的影响。结果表明,在750~800℃之间,Cu与Ti3AlC2之间会发生反应生成TiC相。同时随着温度在650~850℃不断增加,密度和抗弯强度不断增加在850℃达到最大值分别为8.33 g·cm^-3和531.4 MPa,而电阻率先减小在750℃达到最小值1.98×10^-7Ω·m后增加在850℃达到最大值6.47×10^-7Ω·m。Cu/Ti3AlC2复合材料性能随着温度的变化与其致密度和反应生成TiC有着密切的联系。

| Abstract: | Cu/Ti3AlC2 composites were prepared by spark plasma sintering using Ti3AlC2 and Cu powder.The effects of different sintering temperatures on the composites were investigated.The results show that between 750~800℃,Cu and Ti3AlC2 react to form Ti C phase.Simultaneously,as the temperature increases at 650~850℃,the density and flexural strength increase continuously to 850℃and reach a maximum of 8.33 g·cm^-3 and 531.4 MPa,respectively,while the resistivity decreases first at 750℃to a minimum of 1.98×10^-7Ω·m increase to a maximum of 6.47×10^-7Ω·m at 850℃.The properties of Cu/Ti3AlC2 composites are closely related to their density and reaction to form TiC with temperature. |
