Abstract:

采用反应热压烧结法制备了SiC/Ti3SiC2复合材料,研究了热压温度、SiC含量及粒度对SiC/Ti3SiC2复合材料相组成、力学性能以及应力-应变行为的影响。结果表明:热压温度影响SiC/Ti3SiC2复合材料相组成;随着热压温度的提高,复合材料的弯曲强度和断裂韧性提高;随SiC含量的增加,SiC/Ti3SiC2复合材料弯曲强度和断裂韧性提高,当SiC的质量分数为30%时,弯曲强度为371MPa,断裂韧性为6.9MPa·m1/2;但SiC的质量分数达到50%时,由于复合材料含有较多的孔洞,使强度和断裂韧性降低;随着SiC粒度的增大,复合材料易于致密化,使其弯曲强度和断裂韧性提高;SiC/Ti3SiC2复合材料在常温下表现为非脆性断裂。
