Abstract

Abstract—The interaction of components during high-temperature annealing of pressed magnesium and boron powders during the production of the superconducting compound MgB2 is considered in works using standard synthesis technology and hot gas-static pressing technology. In a computer model of crystallization of a binary alloy, the influence of the diffusion of components in the region of the interphase boundary during crystal growth on the morphology of dissipative structures formed during phase transformation was studied. An analysis of the conditions and mechanism of the formation of a “layered” structure that appears during the crystallization of MgB2 from a magnesium melt in the (Mg–B) system has been carried out.
