Abstract

Linear stability of the solid/liquid interface in directional solidification of a multicomponent alloy is examined. The front becomes more unstable as more components are present. The neutral stability boundary displays many minima compared to a single one for two-component alloys. Bounds are presented to guarantee stability in the multicomponent case.
