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 ...
Mg–Nd, Mg–Zn, and Mg–Nd–Zn Thermodynamic description on the miscibility gap
(2013-03-29)
With the consideration of the existence of the metastable miscibility gaps, the thermodynamic parameters of the Mg-based solid solution have been assessed for the Mg–Zn and Mg–Nd systems. The new semi-empirical equation ...
Mn-Nb-Si Thermodynamic assessment
(2013-03-29)
Based on the experimental isothermal sections at 800, 1000, 1700 and 1800 °C and the liquidus projections from both the literature and the present measurements, the ternary Nb–Si–Mo system is thermodynamically assessed ...
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 ...
Hg–Ga-Mg Thermodynamic assessment of phase equilibria
(2013-03-29)
Phase relations in the Mg–Hg–Ga ternary system have been experimentally and thermodynamically studied. At first, the isothermal sections of the Mg–Hg–Ga system in the Mg-rich region at 673 K and 473 K were investigated by ...
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 ...
