ZrB2 Matrix Ceramic Composites by Hot-Pressed and SiC Whisker Reinforced

在烧结温度和压力为1800 ℃和30 MPa条件下热压烧结制备ZrB2-20%(体积分数, 下同)SiCw陶瓷复合材料,并研究两种不同SiC晶须对材料的显微组织与力学性能的影响.结果表明,复合材料的弯曲强度和断裂韧性与SiC晶须的长径比有关,长径比越大材料的性能越好,弯曲强度和断裂韧性最高为651 MPa和5.97 MPa·m1/2;与单相的ZrB2材料及SiC颗粒增强ZrB2复合材料相比,断裂韧性有显著提高;其主要增韧机制为裂纹偏转、晶须桥连和拔出.
