Abstract

In this paper, we consider the interaction of components during high-temperature annealing of compressed magnesium and boron powders during the production of superconducting compound MgB₂ in studies using standard synthesis technology and hot gas-static pressing technology. In a computer model of crystallization of a binary alloy, the effect 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. 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 are analyzed.
