Due to the high thermal stability of these alloys are characterized by high strength to a temperature of 1300 K to 1000 MPa due to the presence of cluster and composite structures. The relationship between the characteristics of the chemical composition - electron density - phase composition - the amount of each phase high entropy alloy. Mechanisms allowing to control the level of the modulus of elasticity, strength and melting in high entropy alloy.Izuchena oxidation kinetics of alloys of Ti-Al-Si-Zr. It is shown that the oxidation rate of these alloys is almost two times smaller than that of a Ti alloy 6242. Heat resistance of superalloys also exceeds 6242 Ti approximately half. The scheme of the temperature dependence of the strain to failure in the alloys with the particles of the second phase, according to which the second phase particles substantially restrict plasticity alloys at temperatures 0,2-0,3Tpl.
