Precipitate coarsening in multicomponent systems
Expressions to obtain composition shifts due to capillarity are presented when the chemical potential shifts of the precipitate phase are taken into account. These are applied to calculate the precipitate coarsening kinetics in multicomponent systems, showing dependence on the solution thermodynamics followed by the continuous phase. 2002 Published by Elsevier Science Ltd. on behalf of Acta Mat...
متن کاملStrain Rate Induced Amorphization in Metallic Nanowires
Using molecular dynamics simulations with a many-body force field, we studied the deformation of metal alloy nanowires subjected to various strain rates. For all strain rates, the Ni nanowire is elastic up to of 7.5% strain with a yield stress of 5.5 GPa, far above that of bulk Ni. At high strain rates, the crystalline phase transforms continuously to an amorphous phase, exhibiting a dramatic c...
متن کاملMilling-induced Amorphization in a Chalcogenide Compound
The mechanism of milling-induced amorphization was studied by investigating the structural evolution during amorphization via high-energy ball milling of a chalcogenide compound, i.e. Ag3PS4 crystal. The gradual decrease in intensity of the XRD diffraction peaks of Ag3PS4 milled for different durations indicates that the degree of amorphization was enhanced by the mechanical milling. The forwar...
متن کاملDislocation-precipitate Interaction in Discrete Dislocation Dynamics
This contribution deals with the numerical simulation of dislocation dynamics by means of parametric mean curvature flow. Dislocations are described as an evolving family of closed and open smooth curves driven by the normal velocity. The equation is solved using direct approach by semi-discrete scheme based on finite difference method. Numerical stability is improved by tangential redistributi...
متن کاملPrecipitate pattern formation in fluctuating media.
Simulation of the Liesegang pattern formation in low concentration gradient is presented using concentration perturbation in a deterministic model. The precipitation process is based on ion-product supersaturation theory (Ostwald's model). In the classical experiments with high initial concentration gradients, appearance time and locations of the band formation are well reproducible. Decreasing...
