Abstract
Relative growth rates are calculated for the instabilities in the shape of spherical, planar, and cylindrical solids immersed in a supercooled melt. Unlike some previous treatments, the theory is not restricted to small values of the undercooling and does not invoke the quasistatic approximation. Numerical results are presented for the case of a solidifying sphere.Keywords
