Prediction of properties of Al2O3-C refractory based on microstructure by an improved generalized self-consistent scheme

摘要

An improved generalized self-consistent scheme (GSCS), which has a simplified computation process, was proposed to predict the properties, based on microstructure, of multiphase materials. The results of the prediction of the elastic modulus, Poisson’s ratio, coefficient of thermal expansion, and coefficient of thermal conductivity of an Al2O3-C refractory using a multiscale homogenization method with this improved GSCS agree with the experimental results. It is found that understanding the microstructure and choosing a suitable matrix for the prediction are very important for prediction accuracy.
