Thermodynamic assessment of Cr–Nb–C and Mn–Nb–C systems
In the present work, an attempt to provide thermodynamic descriptions for the Cr–Nb–C and Mn–Nb–C systems was made. Various descriptions for most of the binary systems had been already available, so a selection between ... -
Interdiffusivities and atomic mobilities in FCC Co–Mo–W alloys
By employing six groups of bulk diffusion couples together with electron probe microanalysis technique, the composition dependence of ternary interdiffusion coefficients in Co-rich fcc Co–Mo–W alloys at 1373 K was determined ... -
Modeling of Fe–W phase diagram using first principles and phonons calculations
In the present work, new descriptions of the thermodynamic properties of the Fe–W system were established based on the Calphad approach using the PARROT module of the Thermo-Calc software. For the present work, existing ... -
Thermodynamic modeling of Laves phases in the Ta–V system: Reassessment using first-principles results
The Ta–V system is an interesting system exhibiting the existence of Laves phases among elements of the same group in the periodic system, and with an unusual order of stability of Laves phase structures at 0 K. Whereas ... -
Computational study of atomic mobility for bcc phase in Ti–Al–Fe system
Experimental diffusion data were critically assessed to develop the atomic mobility for the bcc phase of the Ti–Al–Fe system by using the DICTRA software. Good agreements were obtained from comprehensive comparisons made ... -
First-Principles Calculations, Experimental Study, and Thermodynamic Modeling of the Al-Co-Cr System
The phase relations and thermodynamic properties of the condensed Al-Co-Cr ternary alloy system are investigated using first-principles calculations based on density functional theory (DFT) and phase-equilibria experiments ... -
Experimental study and thermodynamic modeling of the Al–Co–Cr–Ni system
A thermodynamic database for the Al–Co–Cr–Ni system is built via the Calphad method by extrapolating re-assessed ternary subsystems. A minimum number of quaternary parameters are included, which are optimized using ... -
Thermodynamic modeling of Al–Co–Cr, Al–Co–Ni, Co–Cr–Ni ternary systems towards a description for Al–Co–Cr–Ni
The phase relations and thermodynamic properties of the Al–Co–Cr, Al–Co–Ni, Co–Cr–Ni ternary alloys are investigated using first principles calculations based on DFT (density functional theory). Their thermodynamic ... -
Thermodynamic re-modelling of the ternary Al–Cr–Ti system with refined Al–Cr description
In the present paper, the ternary Al–Cr–Ti and binary constituent Al–Cr systems are thermodynamically re-modelled based on new experimental information reported in the literature within the past few years. Few key experiments ... -
Thermodynamic assessment of the ordered B2 phase in the Ti–V–Cr–Al quaternary system
Thermodynamic assessment of the ordered B2 phase in the quaternary Ti–V–Cr–Al system is carried out. A set of self-consistent thermodynamic parameters is presented. A two-sublattice model (Al,Cr,Ti,V )0.5: (Al,Cr,Ti,V )0.5 ... -
The Al–Fe–Mn system revisited—An updated thermodynamic description using the most recent binaries
The so-called TWinning Induced Plasticity (TWIP) steels have gained a lot of attention in the last couple of years due to their excellent mechanical properties; they show very high strength and are at the same time very ... -
Thermodynamic assessment of the Al-Ni system
The sub-lattice model is used to describe the thermodynamic behaviour of the ordered phases existing in the Al-Ni system. The model parameters are derived from an optimisation procedure using all available experimental ... -
Experimental study and thermodynamic modelling of the ternary Al–Ta–Ti system
In the present paper a thermodynamic description of the entire ternary Al–Ta–Ti system is proposed, being obtained by CALPHAD modelling. Dedicated experiments were performed in order to complement literature data on phase ...
