Experimental Investigation and Thermodynamic Assessment of Phase Equilibria at the Ti-Mn side in the Ti-Mn-Mo Ternary System
The phase relationships of the Ti-Mn-Mo ternary system on the Ti-Mn side at 900 and 1000 °C were experimentally studied based on microstructure and phase constituents from the equilibrated alloys using electron probe microanalysis, scanning electron microscopy, and X-ray diffraction. The solubilities of Mo in the βTiMn, TiMn2, TiMn3 and TiMn4 phases of the Ti-Mn system were measured. A three-phase region and seven two-phase regions were experimentally determined. No ternary compounds were found. Based on the experimental data and the thermodynamic descriptions of the three binary sub-systems available in the literature, a set of thermodynamic parameters of the Ti-Mn-Mo ternary system was obtained. The calculated isothermal sections and vertical sections agree well with the experimental results. The calculated liquidus projection and invariant reaction scheme of the Ti-Mn-Mo ternary system are also presented. The present work can provide essential experimental and thermodynamic data for the design of biocompatible medical titanium alloys.
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.
