Phase field simulation of liquid-solid-eutectoid multiple phase transformations of a Fe-C binary alloy

China Foundry, 2020
A new continuous multi-phase transformation field model was established for liquid-solid-eutectoid transformation. Taking Fe-C alloy as an example, the model was used to simulate the evolution of the micromorphology of the liquid-solid phase transition ...

A Phase Field Model for Continuous Clustering on Vector Fields [PDF]

, 2001
A new method for the simplification of flow fields is presented. It is based on continuous clustering. A well-known physical clustering model, the Cahn Hilliard model, which describes phase separation, is modified to reflect the properties of the data to

Phase field simulations in miscibility gaps [PDF]

Calphad, 2009
Abstract Using phase field simulations, it is possible to simulate the dynamics and morphology of immiscible liquids/solids appearing at the miscibility gap of any system. These simulations may also be used to determine the asymptotic compositions of the fluids for a given Gibbs energy.

A phase-field simulation of the solidification process under compression

Journal of Materials Research and Technology, 2021
Semi-solid metal forming processes cover a wide variety of technologies in manufacturing, generally leading to non-dendritic microstructures typified by rosette-like or spherical grains.

Phase-Field Simulation and Dendrite Evolution Analysis of Solidification Process for Cu-W Alloy Contact Materials under Arc Ablation

Metals
Cu-W alloys are widely used in high-voltage circuit breaker contacts due to their high resistance to arc ablation, but few studies have analyzed the microstructure of Cu-W alloys under arc ablation.

Evaluation of the elastic field in phase‐field crystal simulations

PAMM, 2023
AbstractThe phase‐field crystal model (PFC) describes crystal structures at diffusive timescales through a periodic order parameter representing the atomic density. One of its main features is that it naturally incorporates elastic and plastic deformation.

Phase-Field Simulation of Spinodal Decomposition in Mn-Cu Alloys

Metals, 2022
The spinodal decomposition was studied in the aged Mn-40 at. %Cu, Mn-30 at. %Cu, Mn-20 at. %Cu alloys using a phase-field model based on the Cahn–Hillard equation, considering a subregular solution model and the energy contribution of the magnetic ...

Phase field simulation of thermomechanical fracture [PDF]

PAMM, 2009
AbstractIn Francfort and Marigo's variational free‐discontinuity formulation of brittle fracture [1] cracking is regarded as an energy minimization process, where the total energy is minimized with respect to any admissible crack set and displacement field.

Phase-field simulation study of the migration of recrystallization boundaries [PDF]

Physical Review B, 2013
We present simulation results based on a phase-field model that describes the local migration of recrystallization boundaries into varying deformation energy fields. An important finding from the simulations is that the overall migration rate of the recrystallization front can be considerably affected by the variations in the deformed microstructure ...
