Thermodynamic optimization of ternary phase diagrams via Calphad approach is a complex procedure. The success and quality of such a Calphad optimization depend on the reliability of the experimental data and on the scrutiny of the critical evaluation

Experimental data published on the phase relationships in the Al–Ta–Ti system have been critically evaluated and a recommended set of internally consistent phase diagrams is given. The work is performed within the MSIT evaluation programs, partia

Die Konstitution metallischer und keramischer Systeme ist ein wesentlicher Bestandteil der Materialkunde. Schon fruh wurde daher in der DGM der Fachausschuss ,,Konstitution“ unter wesentlicher Beteiligung von G. Petzow gegrundet. Dieser Fachausschu

New experimental measurements of mixing enthalpy and activity of the liquid phase along with the data already taken into account in previous thermodynamic assessments have been used in a reassessment of the thermodynamic parameters of the Mg–Y syst

By using differential thermal analysis, metallography and X-ray examination, the La–Si phase diagram was constructed. La5Si3, La3Si2, La5Si4, LaSi were confirmed. Two lanthanum disilicides were found — LaSi2-a1 (structure type α-GdSi2) and LaSi2

Phase relationships were reinvestigated for the isothermal section of the Ce–Y–Si system at 600°C using X-ray powder diffraction techniques and EMPA. From Rietveld refinements the alloy CeY 4 Si 4 was found to crystallize with the partially diso

The quasibinary MgCu2-MgZn2 system was optimized with the program BINGSS. All phase diagram data and thermodynamic values available in the literature were critically assessed before the optimization. Experimental investigations by EDX of ternary Cu-M

In order to optimise the Nb-Cr system all available thermodynamic and phase diagram data were evaluated. Inconsistent values were not used in the final calculation. The liquid, Nb-bcc and Cr-bcc phases were described by the Redlich-Kister model, whil
