Abstract

The paper discusses the interaction of components during high-temperature annealing of compressed magnesium and boron powders in the production technology of the superconducting compound MgB₂, based on the results presented in previous works that utilized standard synthesis technology and hot isostatic pressing technology. The study investigates the impact of crystal growth kinetics and diffusion of the components at the phase interface on the morphology of dissipative structures formed during phase transformation. A computer model of binary alloy crystallization was used to analyze the conditions and formation mechanism of dendrite-like structures that arise during the crystallization of MgB₂ from the melt of magnesium (Mg–% B).
