Abstract. Ternary Mg-Zn-Ce phase equilibria were investigated by key samples to determine the solubilities, primary crystallizing phases and invariant reactions. Alloys were prepared from pure elements and investigated by DTA/DSC and SEM/EDS.

A consistent thermodynamic Calphad-type model of the ternary Mg-Zn-Ce system is : Chen-nan Chiu, Artem Kozlov, Joachim Gröbner, Rainer Schmid-Fetzer. Abstract. The thermodynamic description of alloy systems has been and still is in terms of phenomenological thermodynamics.

The chemical potential, µ i α, of a component i in the alloy phase α as a function of composition and temperature is in principle a sufficient property to characterize the alloy system. Hence the development of experimental methods specific to alloy thermodynamics has Cited by: 4. A procedure is suggested to identify key sample compositions in n-component alloys, providing the most crucial information with limited experimental effort.

The proposed algorithm furthermore establishes the exact type of reaction equation of the (n + 1) phase invariant equilibria. Predictive calculations of phase equilibria in quaternary Mg-Al-Ca-Sr and quinary Mg-Al-Ca-Sr-Mn alloys Cited by: Measurements of the thermodynamic properties of solid binary alloys have been in progress in our laboratory for several years, and the results of electromotive force studies on the following.

Apart from metals and alloys, the book places special emphasis on the growth of thin films and bulk crystals, which are the two main pillars of modern device and semiconductor technology.

All the presented phenomena are tied back to the basic thermodynamic properties of the materials and to the underlying physical processes for clarity.

The vapor pressure of palladium over nine Pd-Pt alloys was measured by the torsion-effusion method. Calorimetric heat-of-solution measurements were carried out on specimens from the same alloys to derive the enthalpy of formation. The activities and partial and integral free energies at °K, computed from the vapor-pressure measurements, were combined with the integral.

Proceedings of the International Symposium on Thermodynamics of Alloys (delft, the Netherlands, JuneMiedema, A. R.; Rathenau, G. This is a concise introduction to titanium alloys and focuse s on the most relevant aspects for the book, namely the effect of the thermo mechanical processing of titanium alloys and aluminides.

The chapter includes a section on the most common alloys, as the large number of alloys found in the literature can be very confusing. 3. Thermodynamic database.

The alloy studied contains the elements Co, Cr, Fe, Mn, and Ni and in order to perform phase diagram calculations a thermodynamic Calphad-type database with those elements is needed.

Since the alloy contains equal amounts (by mole of atoms) of the elements all boundary systems are, in principle, equally important. Get this from a library.

All the presented phenomena are tied back to the basic thermodynamic properties of the materials and to the underlying physical processes for clarity. X‐ray diffraction and dilation studies have shown that alloys near the stoichiometric TiNi composition undergo transformation into the related phases Ti 2 Ni and TiNi 3 at low temperatures.

The main factors controlling these phase transformations are alloy composition, temperature, and mode of plastic deformation. In plastic deformation, tensile or compressive stressing produced separate and.
