Abstract
An analysis of atomic displacements in V - Cr and V - Mo alloys is mad e by means of computer simulation. In particular, the threshold displa cement energies were determined for various kinds of atoms along vario us crystallographic directions. In alloys, the threshold displacement energy increases (compared to one-component materials) for nearly all crystallographic directions due to the appearance of inhomogeneity in the chains of substituting collisions. Inhomogeneities in these chains play a dominant role in the change of the threshold displacement ener gy if the concentration of substitutional atoms exceeds 5%.
