Thermodynamic assessment of the Co-Mo system
Experimental thermochemical and phase diagram data for the Co-Mo system were assessed. A consistent thermodynamic description, using a Redlich-Kister model for the solution phases and sublattice and line-compound models ... -
A thermodynamic evaluation of the Cr-Ni-W system
An evaluation of the Cr-Ni-W system has been made using a magnetic subregular model for the interstitial solution phases, a multi-sublattice model for the intermetallic phases and an ordinary subregular solution model for ... -
A thermodynamic description of the Ni–Al–Cr–Re system
Thermodynamic properties of the Ni–Re binary system were analyzed using thermodynamic models for the Gibbs energy of individual phases of the system. The model parameters were optimized from limited experimental phase ... -
Experimental and theoretical study of the phase equilibria in the fe-ni-w system
Experimental data on the Fe-Ni-W phase diagram have been obtained at 1273, 1373, 1473, 1573, and 1673 K by means of the diffusion-couple technique and electron microprobe analysis. These data were combined with selected ... -
An optimized diffusion database for the disordered and ordered bcc phases in the binary Fe–Ti system
An assessed mobility database for the disordered A2-bcc and ordered bcc-B2 phases in the binary Fe–Ti system has been constructed using the model of Helander and Ågren [T. Helander, J. Ågren, A phenomenological treatment ... -
A thermodynamic evaluation of the Mo-Ni system
A thermodynamic evaluation of the Mo-Ni system is presented. A set of parameters values describing the Gibbs energy of each phase is given. Calculated quantities are compared with experimental data, and the agreement is ... -
Thermodynamic assessment of the Ni-Ti phase diagram
A new assessment of the thermodynamic properties of the stable phases of the Ni-Ti system is presented, based on the experimental thermochemical and phase diagram data from the literature. Suitable sublattice models are ... -
The influence of magnetic and chemical ordering on the phase diagram of Cr–Fe–Ni
A thermodynamic dataset for the ternary system Cr–Fe–Ni which has been reported in the literature for the range from medium to high temperatures has been supplemented with datasets from the binary sub-systems at lower ... -
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 ... -
Thermodynamic evaluation of the Al–V–C system
The Al–V–C system contains the two ternary compounds V2AlC and V4AlC3 which are of considerable interest for high-temperature applications. The system is so far rather sparsely investigated experimentally and melting ... -
Assessment of the Re–Ta binary system
Using the CALPHAD method, the thermodynamic properties of each phase of the Re–Ta system were optimized using the experimental information on the phase diagram and the thermochemical quantities. A consistent set of parameters ... -
Assessment of diffusion mobility for the bcc phase of the Ti–Al–Cr system
Experimental diffusion data in the literature were critically assessed to develop the diffusion mobility for the bcc phase of the Ti–Al–Cr system by means of a DICTRA-type (Diffusion Controlled Transformation) diffusion ... -
AlTaTi
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 ... -
Al-Mg COST 507 Thermochemical database for light metal alloys
(1998-07)Bearing in mind the alloy categories defined by industrial partners at the beginning of the Action, a matrix was drawn up to define the binary systems forming the building blocks for the evaluation of higher-order systems. ... -
A thermodynamic assessment of the Ni-Al-B system
(2014-11-20)The thermodynamics of the Ni-Al-B system are assessed based on available literature data. Both the Ni-B and Al-B systems were revised to treat B as an interstitial element in a face-centered cubic structure, rather than ... -
