Abstract
We derive an evolution equation governing the cellular structure of a binary alloy having a 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.
