Abstract

We investigated the possibility of metastable phase formation and functional properties of the magnetic system accompanied with floating melt solidification of materials by using the electromagnetic levitation apparatus. Expected for a microgravity experimental apparatus used in an airplane, and then we established and studied the basic technique of this apparatus in detail. As a result, the crystallization of ferromagnetic metastable phase with the high coercive force unreported until now was obtained in the containerless floating melt solidification sample of the Nd-Fe binary alloy. In addition, we investigated the non-equilibrium solidification process in a new high speed cooling curve measurement system and a new result was obtained.
