摘要 采用放电等离子体烧结工艺制备体积分数分别为15%、35%、55%和75%的β-锂霞石/Al复合材料(Euc/Al)。为防止Euc颗粒和Al基体之间的界面反应,将Euc颗粒表面进行ZnO涂覆处理。采用光学显微镜、透射电镜、X射线衍射和热膨胀仪对Euc/Al复合材料的微观组织、相成分和热膨胀性能进行测试和分析。在复合材料中,由于大的各向异性残余应力的作用,形成Euc颗粒的亚稳相。对复合材料进行去应力退火处理后,复合材料中的Euc亚稳相发生逆转变,其对复合材料的热膨胀行为产生显著影响。 采用放电等离子体烧结工艺制备体积分数分别为15%、35%、55%和75%的β-锂霞石/Al复合材料(Euc/Al)。为防止Euc颗粒和Al基体之间的界面反应,将Euc颗粒表面进行ZnO涂覆处理。采用光学显微镜、透射电镜、X射线衍射和热膨胀仪对Euc/Al复合材料的微观组织、相成分和热膨胀性能进行测试和分析。在复合材料中,由于大的各向异性残余应力的作用,形成Euc颗粒的亚稳相。对复合材料进行去应力退火处理后,复合材料中的Euc亚稳相发生逆转变,其对复合材料的热膨胀行为产生显著影响。
