Thermodynamic and mechanical equilibrium morphologies of microasperities on a solid surface

Physics Letters A, 1982
Abstract Micron size tapered asperities having a bent or spiralled appearance have been observed in SEM studies of ion bombarded surfaces. We suggest that these forms arise from the relaxation of surface stress σ on what are initially conical asperities.

Formation of thermodynamically unstable solid solutions in the Cu-Co system by mechanical alloying

Physical Review B, 1993
Cu-Co has been chosen as a model system to study phase formation during mechanical alloying in systems with components exhibiting a positive heat of mixing. Phase formation is monitored by scanning electron microscopy, x-ray diffraction, and calorimetric measurements.

On the thermodynamic foundations of non-linear solid mechanics

International Journal of Non-Linear Mechanics, 1972
Abstract Non-equilibrium thermodynamics with internal variables governed by rate equations is explored as a foundation for non-linear solid mechanics. Rate equations are studied as to type, yielding descriptions of viscoelastic, viscoplastic, and plastic behavior.

New Variational-Lagrangian Irreversible Thermodynamics With Application to Viscous Flow, Reaction–Diffusion, and Solid Mechanics

Advances in Applied Mechanics, 1984
This is a comprehensive survey of theory and application of a new approach to irreversible thermodynamics developed by the author since 1954 in a sequence of papers. From the author's introduction: ''Our purpose here is to present a comprehensive view of a distinct approach to the thermodynamics of irreversible processes that is based on a principle of

Structural and Thermodynamic Insight into Solid State Phase Transition Mechanism of a 1,3,3′-Triketone

Crystal Growth & Design, 2013
A study of a solid state phase transition in dipivaloyl(3-cyclopentylpropanoyl)methane was undertaken by a combination of crystallographic and calorimetric methods. The high temperature polymorph with two molecules in the asymmetric unit and a disordered cyclopentyl group undergoes a reversible phase transition into an ordered structure with a single ...

Thermodynamic properties, mechanical properties and interatomic potential in solids: a Shou-Shi-Ling ( ) game

Continuum Mechanics and Thermodynamics, 2021
Two formulae were developed to express sublimation enthalpy and Young’s modulus on a thermodynamic basis. The first formula reveals how the sublimation enthalpy is correlated with the thermal expansion coefficient and heat capacity of solids, whereas the second formula relates the Young’s modulus with sublimation enthalpy and equilibrium interatomic ...

Influence of Thermodynamics and Diffusion on Reaction Mechanisms during Gas/Solid Reactions

Contributed Papers from MS&T17, 2017
The direct link between microstructure and material properties is the core principle underpinning modern material science and engineering. Phase transformations in solids and solidification of melts have been extensively studied to the point where the key elementary processes, process steps and process variables are well understood.

Thermodynamic analysis and the mechanism of the solid-phase reduction of Cr2O3 with carbon: Part 1

Russian Metallurgy (Metally), 2013
The thermodynamic laws of the interactions in the Cr-O-C system developing in the temperature range from 1273 to 1773 K are considered. The existing opinions concerning the mechanism of the solid-phase reduction of Cr2O3 with carbon are analyzed. The leading role of CO-CO2 gases that relate the solid reagents in this process is found on the basis of ...

Thermodynamic model for solid-state amorphization of pure elements by mechanical-milling

Journal of Non-Crystalline Solids, 2006
Abstract Mechanical-milling induced solid-state amorphization (SSA) has been observed in some covalent metalloids (Si, Ge, Se), but never in pure metals at room temperature. In this paper, a thermodynamic model was proposed for the SSA of the pure elements.
