Experimental techniques for phase diagram determination

Topic description and teaching suggestions: Various thermal analysis techniques: TG, DTA, DSC, complemented by XRD, SEM-EDS and optical microscopy, diffusion couples, Mössbauer, neutron diffraction, all adapted for measurements at high temperatures, are currently employed to determine phase diagrams and to highlight transformations up to the melting point of inorganic materials (alloys, ceramic, and minerals), as well for the study of reaction kinetics (e.g. oxidation of metals, alloys, intermetallics and refractory non-oxide compounds, decomposition of solids, etc.). Give (or refresh where necessary) a brief description of the techniques and illustrate a few selected examples.
