Linear Analysis of Dynamic Instability of Solidification with a Quasiequilibrium Mushy Zone

Dmitri V. Alexandrov

ABSTRACT

Linear analysis of dynamic instability is carried out for a unidirectional solidification of binary melts in the presence of a mushy zone. An equation for the parameter characterizing a time behavior of perturbations is deduced. Regions of stability and instability corresponding to the "hard" and "soft" types of instability evolution are calculated for actual alloys.
