The TiN/TiAl₃/Ti₂AlN composite material is fabricated in the filtration combustion mode in nitrogen of porous samples made of the TiAl intermetallic powder consolidated under thermal vacuum treatment. The weight content of each phase, which was 42% TiN, 35% TiAl₃, 20% Ti₂AlN, and 3% TiAl, is calculated from the X-ray phase analysis data of combustion products. The synthesized composite material containing the Ti₂AlN MAX phase is good electric conductor with the metallic conduction type. Resistivity of the synthesized material is measured according to the standard 4-point dc procedure in a temperature range of 300–1300 K in vacuum 2 × 10^–3 Pa. It is revealed that resistivity increases linearly from 0.35 to 1.25 μΩ m with an increase in temperature. Repeated measurements of this characteristic under subsequent heating–cooling cycles demonstrated the complete coincidence of the results, which evidences the stability of electrical properties of this material in this temperature range.

TiN / TiAl 3 / Ti 2 AlN复合材料的电阻率的温度依赖性

TiN / TiAl ₃ / Ti ₂ AlN复合材料是在过滤燃烧模式下，在由氮气经热真空处理固结的TiAl金属间粉末制成的多孔样品的氮气中以过滤燃烧的方式制备的。各相，这是42％的锡，35％的TiAl的重量含量₃，20％的Ti ₂ AlN，以及3％的TiAl，从燃烧产物的X射线相位分析数据来计算。含有Ti ₂ AlN MAX相的合成复合材料是具有金属导电类型的良好电导体。合成材料的电阻率是根据标准的4点dc程序在2×10 ^–3的真空中于300–1300 K的温度范围内测量的揭示了电阻率随温度的升高从0.35线性增加到1.25μΩm。在随后的加热-冷却循环下重复测量该特性，证明了结果的完全吻合，这证明了该材料在此温度范围内的电性能稳定。
