陶瓷增强金属基复合材料、复相陶瓷等材料自制备温度冷却下来时,不可避免地要产生热应力.这种热应力对材料的力学性能有着重要的影响,因此,陶瓷增强金属基复合材料和复相陶瓷中热应力问题的研究已引起这一领域科学工作者的普遍重视.迄今有关的研究工作主要是以增强相(颗粒等)嵌入到空心基质模型为基础的,这种模型对于从整体上认识复合材料的热应力分布和增强体间相互作用等显得有些不足.本文建立了一个弹性模量和热膨 Ceramic reinforced metal matrix composites, multiphase ceramics and other materials from the preparation temperature cooling down, inevitably have to generate thermal stress.This thermal stress on the mechanical properties of the material has an important impact, therefore, ceramic reinforced metal matrix composites and The research of thermal stress in complex ceramics has attracted the widespread attention of scientists in this field.The research work so far mainly based on the reinforcement phase (particles etc.) embedded in the hollow matrix model, the model for the whole The understanding of the thermal stress distribution of composite materials and enhance the interaction between the body is somewhat inadequate.This paper established a modulus of elasticity and thermal expansion
