Abstract
In this paper, computer simulations of the hardness of ordered and disordered alloys of Cu−Ag and Au−Ag were performed using the Sutton-Chen potential and the GULP software package within several models. In addition, Poisson ratios were estimated. When simulating a chemical disorder, a super-cell containing 108 atoms was built. Numerical experiments have shown that chemical disorder in the studied alloys leads to hardness degradation.
