Based on the recently proposed physically-based segmented model, the descriptions for Gibbs energy of pure Cr and Nb down to 0 K were first established. After that, a thermodynamic re-assessment of binary Cr-Nb system down to 0 K was then performed by taking into account all the experimental phase equilibria and thermodynamic properties. Especially, the experimental heat capacities of Cr2Nb at low...
Based on the recently developed numerical inverse method, high-throughput measurement of the composition-dependent interdiffusivity matrices in the bcc_A2 Fe-Mn-Si alloys at 1173, 1273 and 1373K was performed in the present work. To verify the reliability of the presently determined interdiffusivities, the ternary interdiffusivities evaluated by the traditional Matano-Kirkaldy method at the intersection...
Based on the experimental equilibrium data on spinodal decomposition in the literature together with the newly measured data in the present work, a complete metastable phase diagram for the pseudo-binary c–TiN/c-AlN system was constructed for the first time, from which a self-consistent thermodynamic description was then established by means of CALculation of PHAse Diagram (CALPHAD) method with the...
A novel thermodynamic modeling strategy of stable solid alloy phases is proposed based on segmented regression approach. The model considers several physical effects (e.g. electronic, vibrational, etc.) and is valid from 0K up to the melting temperature. The preceding approach has been applied for several pure elements. Results show good agreement with experimental data at low and high temperatures...
The recently developed Arrhenius formula of a modified Sutherland equation was employed to calculate the self– and impurity diffusivities in liquid Sn, Ag, In and Sb. The reliability of the calculated self– and impurity diffusivities was validated by comparing the presently calculated results with the critically reviewed literature data. Based on the reliable tracer and chemical diffusivities available...
CALPHAD XLIII Conference was held from June 1 to 6, 2014 in Changsha, China, with 85 oral presentations, 120 posters and 5 software demonstrations. 206 participants from 24 countries participated in this conference. The topics covered during the conference were gathered in nine categories: CALPHAD Assessments & Experiment; Modeling and Software; Database Development; Application of CALPHAD Method;...
