第二相SiC颗粒弥散增韧氧化铝陶瓷的残余应力计算

Calculation of Residual Stress of Alumina-base Ceramics Toughened by the Second Disperse SiC Particles

为了从微观的角度解释和说明弥散SiC颗粒通过增韧而达到增强和提高耐磨性的本质原因 ,建立了弥散颗粒分布模型及应力计算模型 。

A distribution model of the second disperse SiC particles and a calculation model of the stress were set up in order to carry out the analysis by micro theory, by which it might throw light on the reasons of high strength and high wear resistance of SiC toughened alumina. The calculation of the residual stress in one-dimension was made.
