Abstract

In this study, the Ti(Mn0.755Al1.246) alloy is obtained for the first time using self-propagating high-temperature synthesis. The obtained material is studied using methods of X-ray diffraction and microstructural analysis. It is shown that the content of the main phase is 98 wt %, and aluminum oxide Al2O3 is also present in the combustion product. Measurement of the temperature dependence of specific electrical resistance in the range from 80 to 1100 K shows that the alloy is characterized by a very low value of the temperature coefficient of resistance ~(0.236–1.15) × 10–4 K–1. The electrical resistance of the material based on Ti(Mn0.755Al1.246) at room temperature is 6.9 μΩ m. The maximum magnetization σs for the product ground to powder is 0.41 A m2/kg.
