- W2293359997 abstract "以自制的高纯Cr_2AlC陶瓷粉体为原料,采用冷压真空烧结技术制备了Cu-15%Cr_2AlC（质量分数）复合材料。研究了不同压制压力、烧结温度及烧结时间对复合材料的电阻率、热导率、摩擦因数以及材料的断裂方式和组织结构的影响。结果表明：随着压制压力的增大、烧结温度的升高,复合材料的电阻率、摩擦因数呈下降趋势,热导率逐渐升高;随着烧结时间延长,复合材料的电阻率逐渐降低,摩擦因数先降低后升高,热导率先升高后降低;复合材料的断裂方式均为脆性断裂;随着烧结温度的提高、烧结时间的延长,Cr_2AlC与Cu发生固溶强化效应,引起Cr_2AlC晶格常数畸变。" @default.
