中文摘要:
      以Ti3AlC2粉和锌铝合金ZA27粉作为原料,采用行星球磨混料加气氛保护烧结工艺制备了Ti3AlC2颗粒增强ZA27复合材料,重点研究了烧结温度对复合材料的相组成、力学性能和显微组织结构的影响。结果表明随烧结温度的升高,复合材料的相对密度、维氏硬度、抗弯强度和抗拉强度都增大, 且在870?C时抗弯强度和抗拉强度都达到最大值,分别为592MPa和324MPa。该温度下Ti3AlC2与ZA27之间发生了微弱的化学反应,有利于改善基体与颗粒增强相之间的界面结合效果。

英文摘要:
      A series of Ti3AlC2/ZA27 composites have been successfully synthesized by mechanical alloying and pressureless sintering, which use the mixed powder of Ti3AlC2 and ZA27 as raw material. The effects of sintering temperature on composition, microstructure and mechanical property were investigated. The results showed that the relative density, Vickers hardness, bending strength and tensile strength were improved with increasing sintering temperature from 600?C to 870?C. Both the bending strength and tensile strength reached the maximum values of 592 MPa and 324MPa, respectively, at the temperature of 870?C. A weak reaction between Ti3AlC2 and ZA27 took palce at 870?C and led to the good bonding between the reinforcements and the matrix.
