Abstract

Based on the results of studies of a number of high-entropy alloys (HEA), the conditions for the formation of Laves phases of type C14 were established. The influence of the electronic concentration of chemical elements on its content, as well as the hardness and modulus of elasticity of hard-soluble HEA with BCC and FCC lattices was estimated. Іt is found that a decrease in the parameters of the crystal lattice of the obtained phase leads to an increase in hardness and elastic modulus of alloys.
