Al–Pt First-principles calculations and thermodynamic modeling
(2013-03-29)
Thermodynamic description of the Al–Pt binary system is modeled by combining first-principles calculations with the CALPHAD method. The four-sublattice and two-sublattice compound energy formalisms are used to model the ...
Fe–Mn and Fe–Mn–C systems Thermodynamics effects on hcp phase
(2013-03-29)
The thermodynamic parameters of the ε (hcp) phase with respect to the γ (fcc) phase in the Fe–Mn system have been re-visited by utilizing the least squares refinement method applied to experimental values of enthalpy and ...
Cu-Pb-Sn Thermodynamic description
(2013-03-29)
A thermodynamic description of the ternary Cu–Pb–Sn system at the Cu–Pb side is presented. The thermodynamic parameters of the sub-systems, Cu–Pb, Cu–Sn and Pb–Sn, are taken from earlier SGTE-based assessments and those ...
Au, Cu, Pd and Pt alloys Mobilities and diffusivities
(2013-03-29)
Based on the CALPHAD technique, the atomic mobilities and diffusivities in fcc Fe–X (X=Ag, Au, Cu, Pd and Pt) alloys have been critically studied. The thermodynamic descriptions and various types of diffusivities are ...
Co-Pt Thermodynamic modeling of fcc order/disorder transformations
(2013-04-01)
The present work reports on a thermodynamic modeling of the Co–Pt system with ordered fcc phases of L10 and L12 structures by means of the CALPHAD method. The liquid, hcp and fcc phases have been modeled as substitutional ...
Al-Cu-Fe Interdiffusivities and atomic mobilities
(2013-04-01)
Using solid/solid diffusion couples and the electron probe microanalysis (EPMA) technique, the interdiffusion coefficients in fcc Cu–Al–Fe alloys at 1273 K were determined by means of Whittle and Green’s method. Based on ...
Ni-Pb-Sb Experimental investigation and thermodynamic prediction
(2013-04-01)
The phase diagram of the ternary Ni–Pb–Sb system was investigated experimentally by differential scanning calorimetry (DSC) and scanning electron microscopy (SEM) with energy dispersive spectrometry (EDS) methods, and ...
Si-Sr thermodynamic reassessment
(2013-04-01)
The Si–Sr binary system has been thermodynamically reassessed in the present work based on the critically reviewed experimental data available in the literature, especially newly published experimental phase diagram data ...
Al-Cu-Y Thermodynamic description
(2013-04-01)
Phase equilibria in the ternary Al–Cu–Y system have been analyzed by coupling the CALPHAD method and first-principles calculations, and a complete thermodynamic description was obtained. The thermodynamic descriptions of ...
Ag-Au-Cu Atomic mobilities and diffusion characteristics
(2013-04-01)
CALPHAD kinetics has evolved to be a well-established discipline, which allows complex non-equilibrium processes to be fully explored. Such a success relies on the use of Redlich–Kister polynomials to describe atomic ...
