Rapid solidification of metals and alloys has developed from an insignificant activity into an industrial practice and an important process for research studies. It is generally brought about by one of the following two methods. The first is by rapid quenching from the melt, e.g. melt spinning. The second method involves undercooling the liquid by a large degree below its melting temperature prior to nucleation. In this way, a large driving force for rapid solidification accumulates due to the large difference in Gibbs free energy between the solid and the liquid state. This book presents on...
