| 摘 要： | 采用热压法制备ＺｒＯ２－ＭｏＳｉ２复合材料。结果表明：复合材料的密度、抗弯强度、断裂韧性受第二相粒子ＺｒＯ２含量的影响；在合理的工艺条件下，复合材料的抗弯强度和断裂韧性较基体ＭｏＳｉ２约可提高１～２倍，分别达到５５０ＭＰａ，９．１ＭＰａ·ｍ１／２。研究认为，材料性能提高的主要原因在于ＺｒＯ２相变增韧及复合材料中存在的残余应力。

| Abstract: | In this paper,ZrO 2-MoSi 2 composites were prepared by hot-press process.The effect of ZrO 2 particle content on the bending strength and fracture toughness and density were studied.In the proper process,the value of the strength and toughness of the composites was 1～2 times more than that of the MoSi 2 matrix,up to 550MPa,9.1MPa·m 1/2 .The main reason for the increased properties was the ZrO 2 transformation toughness and the residual stress. |
