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

open access: yesChina 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 ...

Phase-field modelling of molecular dynamics with diffusive motions

open access: yes, 2022
Recently, phase-field modelling has been expanded to the molecular scale. However, such atomistic phase-field simulation cannot treat diffusive motions of molecules so far. Here, we modify phase-field modelling of molecular dynamics to include rigid body

A phase-field simulation of the solidification process under compression

open access: yesJournal 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 of thermomechanical fracture [PDF]

open access: yesPAMM, 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.

Multi-phase field simulation of multi-grain peritectic transition in multiple phase transformation

open access: yesChina 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.

Evaluation of the elastic field in phase‐field crystal simulations

open access: yesPAMM, 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 and Dendrite Evolution Analysis of Solidification Process for Cu-W Alloy Contact Materials under Arc Ablation

open access: yesMetals
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.

Influence of Phases of Coherence Functions on the Wind Field Simulation Using Spectral Representation Method

open access: yesApplied Sciences, 2022
The wave passage effect is a measure of the wave passage delay due to the apparent velocity of waves, which is one of spatially varying properties of multivariate random processes.
