Abstract: The mechanical properties of glasses in the Ag$_3$AsS$_3$–As2S$_3$ system have been studied by the internal friction method. Measurements of internal friction and shear modulus have been carried out in the temperature interval 80–300 K at deformation frequencies of 10–50 mHz. Relaxation-type maxima of internal friction have been revealed. It has been shown that the concentration-induced variations in the parameters of the mechanical relaxation process in (Ag$_3$AsS$_3$)$_x$(As$_2$S$_3$)$_{100-x}$ glasses observed in the region of 20 at% Ag$_3$AsS$_3$ are of the threshold character. It has been established that this feature can be associated with the variation in the structural unit, which accounts for the process of mechanical energy dissipation within the temperature interval 150–250 K.
