Studies on undercooled metallic melts

The author had the opportunity and pleasure of working with Professor Robert Cahn
at the University of Sussex for a considerable length of time . During this association
several areas of investigation were pursued , notable amongst them being application of
the hole theoretical model of liquids for modelling their viscous behaviour",') and the use
of diamond as a splat cooling substrate !') The enhancement of thermal conductivity
through the use of diamond for the substrate enabled us to produce the glassy state in an
aluminium alloy, preceding the current alloys by nearly two decades . In this paper, we
review the subsequent efforts of the author and his co -workers in the areas of
thermodynamic and viscous behaviour of undercooled liquids and the present status of
amorphous aluminium alloys.
