研究了利用液态反应法制备的TiC颗粒（TiCo）增强铸造Fe-Cr-Ni基复合材料的显微结构和力学性能．该复合材料主要由γ基体和均匀分布的尺寸为1-5μm的球状或多面体状TiCp组成γ／TiCp界面洁净，两相靠近界面的区域内均存在高密度位错（Ti十C）加入量（质量分数）为3％-6％时复合材料的常温和高温拉伸性能比基体合金明显提高，其拉伸断口在800℃时仍能保持韧性断裂特征.
The microstructure and mechanical properties of Fe-Cr-Ni matrix composites reinforced by TiC particles prepared by liquid reaction were investigated. The composite material is mainly composed of γ matrix and spherical or polyhedral TiCp with uniformly distributed size of 1-5μm. The γ / TiCp interface is clean, and the density of high-density dislocations (Ti-C) The tensile strength at room temperature and high temperature of the composites is obviously higher than that of the matrix alloy at the mass fraction of 3% -6%. The tensile fracture of the composite still maintains ductile fracture at 800 ℃.
