Abstract

Refractory (melting point Tm = 2100°C), heat-resistant ruthenium monoaluminide RuAl, lighter (ρ = 7.97 g/cm3) than Ni superalloys, is considered as a promising material for operation at a high temperature and under relatively low loads in high-velocity gas oxidizing flows. This alloy can be used not only at a temperature higher than operating temperature tw inherent in both nickel superalloys and nickel and titanium aluminides, but also at a temperature higher than the melting point of the latter. RuAl is also an ideal candidate for potential use in protective coatings. In the first part of the paper, RuAl-based cast alloys have been considered. In the second part of the paper, the potentialities of obtaining alloys based on RuAl directly from the initial powders of ruthenium and aluminum by combining the temperature–time modes of reactive alloying (RA), as well as the sequence and intensity of pressure application in the course of RA, are considered. The third part of the paper is devoted to studying the potentialities of powders doped with RuAl (NiAl, TiAl) with a preset composition obtained by means of mechanical alloying used as a starting material.
