Peisheng Wang et al.
The Co-V system has been reviewed. Density functional theory (DFT) calculations using the generalized gradient approximation (GGA) were used to obtain the energies for the end-members for all three intermediate phases, Co3V, σ and CoV3. Re...
A method for handling the extrapolation of solid crystalline phases to temperatures far above their melting point [0.03%]

Bo Sundman et al.
Thermodynamic descriptions in databases for applications in computational thermodynamics require representation of the Gibbs energy of stable as well as metastable phases of the pure elements as a basis to model multi-component systems. In ...

Peisheng Wang et al.
The Co-Ta system has been reviewed and the thermodynamic description was re-assessed in the present work. DFT (density functional theory) calculations considering spin polarization were performed to obtain the energies for all end-member co...
Sn-Ag-Cu nanosolders: Melting behavior and phase diagram prediction in the Sn-rich corner of the ternary system [0.03%]
富Sn角附近的Sn-Ag-Cu纳米焊料：熔化行为和相图预测

Ali Roshanghias et al.
Melting temperatures of Sn-Ag-Cu (SAC) alloys in the Sn-rich corner are of interest for lead-free soldering. At the same time, nanoparticle solders with depressed melting temperatures close to the Sn-Pb eutectic temperature have received in...
Enthalpies of formation of Cd-Pr intermetallic compounds and thermodynamic assessment of the Cd-Pr system [0.03%]
Cd-Pr系统中间金属化合物的形成焓及热力学评估
Thomas L Reichmann,Klaus W Richter,Simona Delsante et al.
Thomas L Reichmann et al.
In the present study standard enthalpies of formation were measured by reaction and solution calorimetry at stoichiometric compositions of Cd2Pr, Cd3Pr, Cd58Pr13 and Cd6Pr. The corresponding values were determined to be -46.0, -38.8, -35.2 ...
