采用真空热压法原位形成强化相Al2O3,制备出Al2O3颗粒增强Ti2AlN基复合材料。本文对热压态复合材料样品在室温下不同载荷条件下的维氏硬度进行测量,观察了压痕裂纹的形貌,应用压痕方程得出了复合材料的断裂韧性。并对热压态复合材料样品在不同温度下的压缩变形进行了研究,观察了不同变形量样品的变形后形貌。

Al2O3/Ti2 AlN composites were prepared by vacuum hot pressing,which Al2O3 particles as strengthening phase were in situ formed.In this paper,the Vickers hardness of hot-pressed composites under different loads at room temperature was measured,the morphology of indentation cracks was observed,and the fracture toughness of composites was obtained by indentation equation.The compression deformation of as hot-pressed composites at different temperatures was studied,and the morpholog...
