Abstract
AbstractA new method based on Zener relaxation is elaborated for the determination of substitutional interactions in metal solid solutions. The method consists in computer simulation of temperatures of internal friction peaks taking into account the different values of effective interchange energies. Then comparison between the calculated spectra and the experimental ones is performed. It is suggested that substitutional interaction affects the atomic arrangement in creating short‐range order and shifts the energy of the substitutional atom and therefore the activation energy of internal friction. Experimental parameters of Zener relaxation are used to study the interaction energies of Cu‐Zn, AuAg, and CuAl alloys. The energies are close to those determined by diffuse scattering of X‐rays or neutrons.
