摘要： 基于残余应力增韧机制,建立了当TP>Tm时陶瓷材料增强相的极限含量模型,并结合SiC/TiB2颗粒复合陶瓷材料进行了验证与应用.以此为基础,建立了考虑基体颗粒尺寸与粒径配比时的增强相极限体积含量的模型.这些模型的建立对于陶瓷材料的组分设计和微观结构设计均具有重要的实际应用价值.

Abstract: Based on the toughening mechanism of residual thermal-stresses, a model is built for the calculation of the critical volume content of the reinforcement phase in ceramic materials when TP> Tm. The model has been proved valid through its applications in SiC/TiB2 ceramic material. Next, two models are established for the determination of the critical volume content of the reinforcement phase when the particle size of the matrix and the ratio of the particle size of the reinforcement phase and the matrix are considered. Models built here will find a practically application in the composition designing and the micro-structural designing of ceramic materials.

Key words: model, ceramic material, residual thermal-stress, toughening mechanism, critical volume content
