Phase field simulation of dendritic microstructure in additively manufactured titanium alloy [PDF]
, 2019 Additive manufacturing (AM) processes for metals, such as selective laser sintering and electron beam melting, involve rapid solidification process. The microstructure of the fabricated material and its properties strongly depend on the solidification ...

Multi-phase field simulation of multi-grain peritectic transition in multiple phase transformation
China Foundry, 2020 Taking Fe-C binary alloy as an example, based on the multi-phase field model, the nucleation and growth of δ phase, peritectic reaction, peritectic transformation, and the growth of subsequent austenite are simulated.

Observation of Spin-Orbit Berry's Phase in Magnetoresistance of a Two-Dimensional Hole Anti-dot System [PDF]
, 2007 We report observation of spin-orbit Berry's phase in the Aharonov-Bohm (AB) type oscillation of weak field magnetoresistance in an anti-dot lattice (ADL) of a two-dimensional hole system. An AB-type oscillation is superposed on the commensurability peak,

Accelerating fracture simulation with phase field methods based on Drucker-Prager criterion
Frontiers in Physics, 2023 The paper presents a framework for accelerating the phase field modeling of compressive failure of rocks. In this study, the Drucker-Prager failure surface is taken into account in the phase field model to characterize the tension-compression asymmetry ...

Phase field simulations in ferroelectric materials [PDF]
PAMM, 2006 AbstractThe hindering of domain wall movement by defects in ferroelectric materials is closely connected to electric fatigue. A movable domain wall in a ferroelectric material in most cases is modelled as a singular surface which allows the use of configurational forces.

Another mean field treatment in the strong coupling limit of lattice QCD [PDF]
, 2011 We discuss the QCD phase diagram in the strong coupling limit of lattice QCD by using a new type of mean field coming from the next-to-leading order of the large dimensional expansion.

Multicomponent alloy solidification: Phase-field modeling and simulations
Physical Review E, 2005 A general formulation of phase-field models for nonisothermal solidification in multicomponent and multiphase alloy systems is derived from an entropy functional in a thermodynamically consistent way. General expressions for the free energy densities, for multicomponent diffusion coefficients, and for both weak and faceted types of surface energy and ...
