Experimental Determination of Phase Equilibria in the Mn-Zn Binary System
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 β, ε, and δ phases. The β-B2 single-phase region could not be confirmed in the studied system because a disordered body-centered cubic structure, which is identical to the δMn phase, was confirmed in a quenched sample from the previously proposed region of β phase. The ε phase has been controversial whether the phase is separated into ε, ε1, and ε2 phases or not. By studying a diffusion couple and several alloy compositions, it was established that the ε, ε1, and ε2 phases are not separate and comprise a single ε phase. Furthermore, the δ phase is not present in the Zn-rich region of the system because the corresponding invariant reactions were not detected via thermal analysis.
期刊介绍：
The most trusted journal for phase equilibria and thermodynamic research, ASM International''s Journal of Phase Equilibria and Diffusion features critical phase diagram evaluations on scientifically and industrially important alloy systems, authored by international experts.
The Journal of Phase Equilibria and Diffusion is critically reviewed and contains basic and applied research results, a survey of current literature and other pertinent articles. The journal covers the significance of diagrams as well as new research techniques, equipment, data evaluation, nomenclature, presentation and other aspects of phase diagram preparation and use.
Content includes information on phenomena such as kinetic control of equilibrium, coherency effects, impurity effects, and thermodynamic and crystallographic characteristics. The journal updates systems previously published in the Bulletin of Alloy Phase Diagrams as new data are discovered.
