【摘要】 分析了金属－陶瓷梯度材料的微观结构特征，并用Ｅｓｈｅｌｂｙ等效原理和Ｍｏｒｉ－Ｔａｎａｋａ平均场理论导出了梯度材料性能预测的三相理论公式．在对性能预测的基础上，用有限元法计算了ＭｇＯ／Ｎｉ梯度材料体系的制备热应力；得到了一些有意义的结论．更多还原

【Abstract】 Eshelby’s epuivalent inclusion method and a three-phase mean-field micromechanical model are applied to evaluating the thermomechanical properties of the ceramic-metal gradient material.The thermal stness generated during cooling from sintering temperature is analyzed by finite element method. According to the numerical results for constituent distribution,a MgO/Ni FGM with thermal stress relaxation has been obtained.更多还原
