Abstract

Stability of the interphase boundary during the oriented crystallization of a binary melt was studied with an allowance of the external temperature gradient. It is demonstrated that the interphase boundary is unstable if the system composition is close to eutectic. The instability development leads to a rodlike (or platelike) periodic distribution of components in the bulk of the solid phase. Dependence of the period of this structure on the phase boundary velocity is determined.
