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