A Chemical Potential Probe to Determine the Solubility of Hydrogen in Metals: An Example with Copper
Journal of Phase Equilibria and Diffusion - - 2020
A probe has been developed to determine the solubility of hydrogen in metals. The method is based on mass balance and high-pressure hydrogen produced in situ partitioning between a zirconium probe and the metal. As an example, the solubility of hydrogen in copper, SH in Cu, has been determined between 350 and 450 °C:

Kinetics of transformation during supersaturation and aging of the Al-4.7mass%Cu alloy: Grain size, dilatometric, and differential thermal analysis studies
Journal of Phase Equilibria and Diffusion - Tập 26 - Trang 555-560 - 2005
The processes taking place during supersaturation of the Al-4.7mass%Cu alloy have been studied by the methods of quantitative metallography and dilatometry. The grain growth activation energy was about 95 kJ/mol, and the exponent of time, n, was close to 0.4. Dissolution of precipitates caused two-stage shrinkage of the sample, which had activation energies of 90 kJ/mol (first stage, n=0.8) and 63...... hiện toàn bộ
Phase Diagram for the System Cu(NO3)2-Al(NO3)3-H2O Ternary System Between 10 and 50 °C
Journal of Phase Equilibria and Diffusion - - 2012
The solid-liquid equilibria of the ternary system H2O-Cu(NO3)2-Al(NO3)3 were studied by using a synthetic method based on conductivity measurements. Five isotherms between 10 and 50 °C were established and stoichiometric phases which appear are, respectively: At 10 and 20 °C: Al(NO3)3·9H2O and Cu(NO3)2·6H2O. At 30, 40, and 50 °C: Al(NO3)3·9H2O and Cu(NO3)2·3H2O.
System Ho-Rh-O: Phase Equilibria, Chemical Potentials and Gibbs Energy of Formation of HoRhO3
Journal of Phase Equilibria and Diffusion - Tập 33 - Trang 429-436 - 2012
The thermodynamic properties of the HoRhO3 were determined in the temperature range from 900 to 1300 K by using a solid-state electrochemical cell incorporating calcia-stabilized zirconia as the electrolyte. The standard Gibbs free energy of formation of orthorhombic perovskite HoRhO3, from Ho2O3 with C-rare earth structure and Rh2O3 with orthorhombic structure, can be expressed by the equation;

Multiscale Entropy and Its Implications to Critical Phenomena, Emergent Behaviors, and Information
Journal of Phase Equilibria and Diffusion - Tập 40 - Trang 508-521 - 2019
Thermodynamics of critical phenomena in a system is well understood in terms of the divergence of molar quantities with respect to potentials. However, the prediction and the microscopic mechanisms of critical points and the associated property anomaly remain elusive. It is shown that while the critical point is typically considered to represent the limit of stability of a system when the system i...... hiện toàn bộ
Mössbauer investigation of Sn diffusion and segregation in grain boundaries of polycrystalline Nb
Journal of Phase Equilibria and Diffusion - Tập 26 - Trang 510-515 - 2005
The parameters of nuclear γ resonance (Mössbauer) spectra on 119mSn nuclei inserted into grain boundaries of polycrystalline Nb have been determined at the annealing temperatures of 680 to 994 K [0.25–0.36 melting temperature (T
m)]. Two components are observed in the nuclear emission γ resonance spectra at all of the annealing temperatures considered. One of them (component 1) is suggested to res...... hiện toàn bộ
