摘要 基于细观力学理论,提出计算氧化铝-碳耐火材料(铝碳材料)弹性模量的Mori-Tanaka方法,并探讨了各组分对其值的影响。首先,通过特定的实验并利用Mori-Tanaka方法,计算出铝碳材料中各相的弹性常数;然后,分别采用单尺度和多尺度分析,对铝碳材料弹性模量进行预测,并将预测值与实验结果进行对比。结果表明:根据铝碳材料的微观结构选择合适的基体,对预测值的准确性很重要;采用Mori-Tanaka方法并结合多尺度分析可有效预测铝碳材料的弹性模量,其值主要取决于连续的多孔碳相。 Based on the theory of micromechanics, an approach has been put forward to calculate the elastic modulus of Al2O3-C refractory using Mori-Tanaka method, and each component influencing the value has also been discussed about. First, each phase's elastic constant in the Al2O3-C material was calculated through specific experiments and the using of Mori-Tanaka method. Then, the elastic modulus of Al2O3-C refractory was predicted by either single-scale or multi-scale analysis, and the predicted values were compared with experimental outcomes. The results show that it's very important for the accuracy of the predicting value of Al2O3-C refractory to choose a suitable matrix based on its microstructure; the elastic modulus of Al2O3-C refractory can be effectively predicted by using Mori-Tanaka method combined with multi-scale analysis; its value mainly depends on the continuous porosity carbon phase.
