Orbital Processing of Aligned Magnetic Composites

Abstract

Experiments will be conducted on the space shuttle in which aligned, two-phase magnetic composites will be grown by plane front directional solidification. The objectives are to: (1) identify and quantitatively evaluate the influences of gravitationally driven thermo-solutal convection on contained plane front solidification of binary, eutectic, off-eutectic, and peritectic magnetic composites; (2) to evaluate the effectiveness of micro-g processing as a means of damping convection; and (3) to evaluate the uniqueness of micro-g processing relative to the best of terrestrial convection damping.
