On strength of monocrystalline alloys of complex composition based on iron

Abstract

We considered strength of an extended cell simulating the structure of a high-entropy crystal alloy сcontaining iron. Atoms of five chemical elements, including iron, are randomly distributed within the cell. Calculations of cell tensile strength were carried out by using a complex of quantum chemical programs ADF. It is shown that for any arrangement of atoms in the cell, its strength is always less than the strength of the cell consisting only of iron atoms.We considered strength of an extended cell simulating the structure of a high-entropy crystal alloy сcontaining iron.
