DISTINCT RELAXATION DYNAMICS AT ROOM TEMPERATURE IN METALLIC GLASS

ABSTRACT
In this article we suggest the equations for the distinct relation processes at room temperature in metallic glass for the first time. We consider the Kohlrausch-Williams-Watts decay laws with the stretching exponents values of l = 3/5 and l = 3/7. It provides a new insight to the comprehensive understanding of the stretched exponential decay law at room temperature in metallic glass.
