摘要：

Phase equilibria in the Mn-Zn binary system were experimentally determined by chemical composition examination, crystal structure determination, and thermal analysis. Major changes were detected for the beta, epsilon, and delta phases. The beta-B2 single-phase region could not be confirmed in the studied system because a disordered body-centered cubic structure, which is identical to the delta Mn phase, was confirmed in a quenched sample from the previously proposed region of beta phase. The epsilon phase has been controversial whether the phase is separated into epsilon, epsilon 1, and epsilon 2 phases or not. By studying a diffusion couple and several alloy compositions, it was established that the epsilon, epsilon 1, and epsilon 2 phases are not separate and comprise a single epsilon phase. Furthermore, the delta phase is not present in the Zn-rich region of the system because the corresponding invariant reactions were not detected via thermal analysis.
