THERMAL EVIDENCE OF A GLASS TRANSITION IN GOLD-SILICON-GERMANIUM ALLOY

Abstract

The specific heat of a ``splat''‐formed amorphous alloy of gold‐silicon‐germanium exhibits a very steep rise with increasing temperature near 295°K to a peak and then begins to fall before crystallization occurs. These last C_p values fall on a reasonable extrapolation of the high temperature C_p‐T relation found for the liquid alloy. These results are attributed to a glass → liquid transition in this metal system.
