摘　　要：本文采用液相法和热压烧结制备出Al2O3/Al复合材料,并利用DSC/TG、SEM、显维硬度计及万能试验机测试研究了复合材料的热学性能、微观结构及力学性能。结果表明,引入Al后复合陶瓷的断裂韧性有显著提高。A1203/A1 composite materials were synthesized tics,microstructure and mechanical properties of the tester and universal testing machine. The results showed higher than that of monolithic A1203. by wet method and hot-pressing. Thermodynamic characteris- composite were studied by DSC/TG, SEM, microscope hardness that fracture toughness of the A1203/A1 composite was much
