Influence of Thermodynamics and Diffusion on Reaction Mechanisms during Gas/Solid Reactions
Contributed Papers from MS&T17, 2017The 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 and mechanical properties of Ce1−xHfxO2 (x=0–0.10) solid solutions
Journal of Nuclear Materials, 2001Abstract Thermal expansion and mechanical properties of Ce 1− x Hf x O 2 ( x =0–0.10) solid solutions were measured from 100 to 850 K by TMA and from 180 to 303 K by ultrasonic pulse methods, as a function of temperature and hafnium concentration.

Thermodynamic analysis and the mechanism of the solid-phase reduction of Cr2O3 with carbon: Part 1
Russian Metallurgy (Metally), 2013The 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, 2006Abstract 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.

Thermodynamics and kinetics of the growth mechanism of vapor–liquid–solid grown nanowires
Journal of Crystal Growth, 2015Abstract Nanowires are widely regarded as building blocks for next-generation devices because of their unique characteristics, particularly their morphology. The vapor–liquid–solid (VLS) system has attracted much attention as a standard method for obtaining nanowires.

The nanocrystalline Cu-5wt.%Cr alloy powders were prepared by mechanical alloying. The structural changes were characterized by X-ray diffraction (XRD) technique. A thermodynamic analysis was carried out to predict the change in the solubility limit of this system. It was found that the energy resulting from the MA process is sufficient to increase the

Steady flow of a multicomponent, incompressible fluid through a connected, solid-like network is considered. ’The network acquires a finite deformation, bears the extra stresses required for mechanical balance, but does not flow. It constitutes at least one thermodynamic component and, in terms of the thermodynamics of irreversible processes, the ...

Thermal decomposition of supersaturated single-phase body-centered cubic (bcc) Fe100−xZnx(5≤x≤65 at.%) solid solutions, processed via mechanical alloying of high-purity metal powders, was investigated using x-ray diffraction and differential scanning calorimetry (DSC).

Solid solution mechanism and thermodynamic properties of Ti–Re alloy system: Experiment and theory
Intermetallics, 2007Abstract Button ingots of Ti100−xRex (x = 4.26, 13.87, 27.78, 47.48 and 73.88 at.%) alloy samples were prepared by an arc melting method. The analyses of X-ray diffraction (XRD) patterns were used to estimate the lattice parameter of β-Ti, the results indicated that the lattice constant of β-Ti decreased with increasing Re content. The solid solution
