Kinetics of structural relaxation in metallic glasses. [PdGe; FeNiPB]

PDF Version Also Available for Download.

Description

When a metallic glass is annealed at temperatures below the glass transition temperature its structure changes with time. This structural change is observed to have an irreversible component and a reversible component. Our work has concentrated on studying the reversible component of the structural relaxation. In this paper the reversible component is called chemical short-range order (CSRO) and the irreversible components topological short-range order (TSRO). It is believed important to determine if the spectrum of relaxation times has fine structure. Experiments have been carried out to obtain the maximum possible detail about the kinetic behavior of the CSRO changes. Also ... continued below

It is believed important to determine if the spectrum of relaxation times has fine structure. Experiments have been carried out to obtain the maximum possible detail about the kinetic behavior of the CSRO changes. Also a new method of analysis of the response curve, referred to as direct spectrum analysis, has been used to resolve fine structure in the spectrum of relaxation times.
