Abstract
The physical, mechanical and tribological properties of cast multicomponent high-entropy boron-doped alloys obtained by vacuum-arc melting are studied. It was found that cast multicomponent high-entropy alloys doped with boron have a hardness of 20-30 GPа and a modulus of elasticity of 400-600 GPа. Alloying high-entropy alloys with a Borut lab6 mixture increases the hardness to 35-45 GPа and the modulus of elasticity to 700-780 GPа. The possibility of setting the coefficient of conversion of hardness to the yield strength knowing the elastic modulus of the material is shown.Alloying high-entropy alloys with boron significantly improves their heat resistance. Thus, the high-entropy tihfnbtamo alloy with the addition of 2% boron reduces the hardness from 13.0 GPа at 20 oC to 8.5 GPа at 900 oC.
