Directional solidification of magnetic composites
Abstract
The directional solidification of three samples of eutectic Bi/MnBi during a low-g interval aboard the SPAR 6 flight is compared with solidification of comparison samples in a 1 g environment under identical furnace velocity and thermal conditions. Plane front directional solidification eutectic Bi/MnBi composites prepared at 1 g over a range of growth velocities, thermal gradients, and solidification orientations with respect to the gravity vector are compared with the samples prepared in space. Morphological analyses and the magnetic properties of the flight samples are compared with the samples obtained at 1 g.
