Based on molecular dynamics and Monte Carlo simulation, the distribution of chemical elements near free surfaces of various crystallographic orientations in high-entropy CoCrFeMnNi alloys was investigated. It is shown that for studied stoichiometric compositions of the alloy it has a different character and differently affects the mechanical characteristics and the defect structure of alloys subjected to uniaxial tension. This is due to the different influence of each element on the elastic modulus of the alloy. Segregation has a greater effect on the Young's modulus and elastic limit for Co30Cr30Fe10Mn10Ni20, while the resulting defect structures have more differences for Co10Cr10Fe30Mn30Ni20. |
