Shear stress relaxation is studied in glasses of similar chemical composition of the system Pd – Cu – Ni – P, whose melts differ considerably with respect to glass-forming capacity. It is demonstrated that glass, whose melt develops considerable glass-forming capacity, always relaxes more slowly. The result obtained is discussed in connection with the possible reasons for glass formation and homogeneous plastic flow of metallic glasses.
