Cell Shapes in Directional Solidification : a Global Study
نویسندگان
چکیده
We experimentally characterize the whole shape of growth cells in directional solidification, from their tip to their grooves, and in a large domain of control parameter. For this a library of cell shapes is determined and fitted to a class of definite shape functions. This first global characterization of cell geometry in both the real space and the control parameter space provides a firm ground for testing or improving theories or simulations of directional growth in the cellular to near dendritic regime.

A Fixed-Grid Front-Tracking Algorithm for Solidification Problems. Part II - Directional Solidification with Melt Convection
A numerical study of directional solidification has been performed using a fixed-grid front-tracking algorithm. The directional solidification of pure tin, as well as the horizontal Bridgman growth of pure succinonitrile, were investigated. In both cases, the growth front was stable and non-dendritic, but was significantly distorted by the influence of convection in the melt and, for the Bridgm...
متن کاملStability and shapes of cellular profiles in directional solidification: expansion and matching methods
Ideas based on constitutional supercooling suggest that the periodic steady state cellular patterns seen in the directional solidification of systems with small partition coefficient may be unstable if the impurity concentration in the melt just in front of the tips falls into the two phase (miscibility gap) region of the phase diagram. This gives a simple stability criterion relating the posit...
