由于TiC熔点高、比重小、强度好、耐高温，TiC基复合材料如Ni-Mo-TiC、Ni-Cr-TiC等已研究用作高温结构材料，但这些材料的高温强度仍不如镍基高温合金，因此只用作切削工具。铌和钼作TiC中稳定的第二相来提高TiC的低温断裂韧性，而且从状态图上可见TiC、Nb、Mo在很宽的成分范围
TiC-based composites such as Ni-Mo-TiC and Ni-Cr-TiC have been studied as high-temperature structural materials because of their high melting point, small specific gravity, high strength and high temperature resistance. However, Alloy, therefore only used as a cutting tool. Niobium and molybdenum as TiC stable second phase to improve the low temperature fracture toughness of TiC, but also from the state diagram shows TiC, Nb, Mo in a wide range of composition
