Thermodynamic Description of Ternary Fe-B-X Systems. Part 5: Fe-B-Si [PDF]

open access: yesArchives of Metallurgy and Materials, 2019
Thermodynamic descriptions of the ternary Fe-B-Si system and its binary sub-system, B-Si, are developed in the context of a new Fe-B-X (X = Cr, Ni, Mn, V, Si, Ti, C) database.

Thermodynamics “beyond” local equilibrium [PDF]

open access: yesProceedings of the National Academy of Sciences, 2001
Nonequilibrium thermodynamics has shown its applicability in a wide variety of different situations pertaining to fields such as physics, chemistry, biology, and engineering. As successful as it is, however, its current formulation considers only systems close to equilibrium, those satisfying the so-called local equilibrium hypothesis.

Non-equilibrium Statistical Mechanics of Two-dimensional Vortices [PDF]

open access: yes, 2018
It has been observed empirically that two dimensional vortices tend to cluster forming a giant vortex. To account for this observation Onsager introduced a concept of negative absolute temperature in equilibrium statistical mechanics.

Thermodynamic Equilibrium in the Expanding Universe [PDF]

open access: yesGeneral Relativity and Gravitation, 1999
We show that a relativistic gas may be at ``global'' equilibrium in the expanding universe for any equation of state $0 < p \leq /3$, provided that the gas particles move under the influence of a self-interacting, effective one-particle force in between elastic binary collisions.

Evaluation of Thermodynamic Parameters of 2, 4-Dichlorophenoxyacetic Acid (2, 4-D) Adsorption

open access: yesJournal of Chemistry, 2013
Thermodynamic parameters of 2, 4-Dichlorophenoxyacetic acid (2, 4-D) adsorption were evaluated by studying the adsorption equilibrium and kinetics of 2, 4-D at different temperatures.

Condições de equilíbrio termodinâmico: a função disponibilidade

open access: yesQuímica Nova, 2011
The thermodynamic equilibrium is a state defined by conditions which depend upon some characteristics of the system. It requires thermal, mechanical, chemical and phase equilibrium.

The thermodynamics of phase equilibrium [PDF]

open access: yesAnnals of Physics, 1961
Abstract Thermodynamics is usually subdivided into a theory dealing with equilibrium and into one concerned with irreversible processes. In the present paper this subdibvision is carried further and the Gibbsian thermodynamics of phase equilibrium is distinguished from the thermodynamics of Clausius and Kelvin.

Thermodynamic Description of Ternary Fe-B-X Systems. Part 6: Fe-B-Ti [PDF]

open access: yesArchives of Metallurgy and Materials, 2019
Thermodynamic optimizations of the ternary Fe-B-Ti system and its binary sub-system, B-Ti are presented. The thermodynamic descriptions of the other binaries, Fe-Ti and Fe-B, are taken from the earlier studies slightly modifying the Fe-Ti system ...

Thermodynamic Insight into the Equilibrium Component Prediction in the Al-Ti-Ca-Oxide System [PDF]

open access: yesArchives of Metallurgy and Materials, 2023
The prediction of equilibrium components for chemical reactions is a considerable section in the metallurgical industry. According to the ion and molecule coexistence theory (IMCT), a modified mass action concentration model based on a thermodynamic ...
