基于第二抗热震因子的BNNTs/Si3N4复合材料抗热震性能评价
|
Abstract:
利用Kingery抗热震断裂理论构建了氮化硼纳米管（BNNTs）强韧化陶瓷复合材料的第二抗热震因子模型，通过真空热压烧结法制备了BNNTs质量分数分别为0.5wt%、1.0wt%、1.5wt%和2.0wt%的BNNTs/Si3N4复合材料，并采用预制裂纹法测试了复合材料的抗热震性能，测试结果证实了在平稳状态下模型的正确性。结果表明，BNNTs的存在使复合材料第二抗热震因子增大，抗热震性能提升。分布在晶界上的BNNTs起到裂纹钉扎、桥联和裂纹偏转作用，增加了裂纹扩展的阻力，从而有效提高了BNNTs/Si3N4复合材料抗热震断裂能力。 The second heat shock factor model of BNNTs reinforced ceramic composites was constructed based on Kingery thermal shock theory. The BNNTs/Si3N4 composites with weight fractions of 0.5wt%, 1.0wt%, 1.5wt% and 2.0wt% were prepared by hot pressed sintering process. The thermal shock resistance of the composite materials was tested by indentation method, verifying the second heat shock factor model in the steady state. The results indicate that the thermal shock performance of the material is enhanced by the BNNTs, with the increase of the second heat shock factor. Because the BNNTs which are distributed on the grain boundary make the crack pinned, bridged, and deflected, the crack propagation resistance is increased. 国家自然科学基金（51372101；51405195）；山东省优秀中青年科学家科研奖励基金（ZR2016EMB01）；泰山学者工程专项经费
