摘　　要：根据TiC颗粒强化铁基复合材料的显微组织观察，按照复相材料的强化理论估计了TiC增强体粒子的加入对钛基体的模量强化和基体强化作用，接材料屈服准则估计了复合材料的屈服强度共同试验结果进行了比较。The microstructure of a titanium alloy matrix composite with 10 vol % TiC particles was observed. Based on strengtheningmechanism of a multiphase alloy, various microstructural strengthening behaviours in the composite are estimated. The Mises yieldcriterion is used for estamating the combined modulus strengthening and matrix strengthening. The predlcted yield strength is comPared to the observed yield strength of the composite.
