Abstract

The dependence of the solute atom energy on the homogeneous strain is derived by expanding the energy of the binary alloy to the second order in the solute concentration and the homogeneous strain components. The energy change is found to be proportional to the solute induced stress. An ab-initio method is then applied to calculate the solute induced stress for Cu, Fe, Li, Mg, Mn, Si, and Zn solute atoms in aluminum.
