摘要：
The as-cast Fe40Mn40Co10Cr10-based (in at.%) high-entropy alloys were doped with different amounts of V and N. It was shown that a certain percentage of V and N cause significant strengthening due to the V2N-type nitrides precipitation. The precipitation-strengthened alloy with 2 at.% V and 1 at.% N had yield strength of 440/940 MPa and uniform elongation of 36/18 % at 293/77 K. Experimental data on the phase composition of the alloys agree reasonably with the CALPHAD predictions.
