Phase diagrams play critical roles in materials science and other engineering fields. Three-dimensional (3D) ternary phase diagrams outweigh traditional two-dimensional ones for better visualization and are good tools to help students understand ternary phase diagrams. As part of the five year project to produce a web-based tutorial for ternary phase diagrams funded by FeMET, five 3D hypothetical ternary phase diagrams modules, including ternary isomorphous, ternary unlimited solid solubility eutectic, ternary limited solid solubility eutectic, ternary peritectic, and one isothermal and two limited solid solubility eutectic, have been constructed by utilizing the software of AutoCAD™ and SolidWorks™. The process for constructing space models of the above systems has been determined. With the newly developed method different 3D phase regions can be extruded and cut both horizontally (isothermal sections) and vertically (isoplethal sections), which will help individuals find the phase relationships inside the complex ternary phase diagrams. All modules of 3D ternary phase diagrams will be incorporated to webpages. Interactivity features such as an interactive Gibbs-Composition (G-X) graph, structure transformation during solidification process at the micro-level, and interactive ternary eutectic reactions have also been created. In addition, three 3D liquidus surfaces of phase diagrams of real systems are created utilizing the thermodynamic software and included as supplemental materials for individuals working in industry. The user-friendly web-based tutorial will be available worldwide free of charge, when completed.
