The authors derive an evolution equation governing the cellular structure of a binary alloy having small segregation coefficient. This equation, applicable to long-wave instabilities of a planar interface, incorporates coupled morphological instabilities and buoyancy effects. The presence of buoyancy can inhibit the onset of the cellular structure by effectively magnifying the segregation and diffusion. Further, the authors discuss the preferred directions for cellular growth.
