On the Relationship and Distinction Between Atomic Density and Coordination Number in Describing Grain Boundaries
Reza Darvishi Kamachali, Theophilus Wallis
Crystal defects are often rationalized through broken-bond counting via the nearest neighbor coordination number. In this work, we highlight that this perspective overlooks intrins…
PINNs-MPF: A Physics-Informed Neural Network Framework for Multi-Phase-Field Simulation of Interface Dynamics
Seifallah Elfetni, Reza Darvishi Kamachali
We present an application of Physics-Informed Neural Networks to handle MultiPhase-Field simulations of microstructure evolution. It has been showcased that a combination of optimi…
Elastic energy of multi-component solid solutions and strain origins of phase stability in high-entropy alloys
Reza Darvishi Kamachali, Lei Wang
The elastic energy of mixing for multi-component solid solutions is derived by generalizing Eshelby's sphere-in-hole model for binary alloys. By surveying the dependence of the ela…
Revealing in-plane grain boundary composition features through machine learning from atom probe tomography data
Xuyang Zhou, Ye Wei, Markus Kühbach +6
Grain boundaries (GBs) are planar lattice defects that govern the properties of many types of polycrystalline materials. Hence, their structures have been investigated in great det…
Surface-Induced Phase Transition During Coalescence of Au Nanoparticles: A Molecular Dynamics Simulation Study
Reza Darvishi Kamachali
In this study, the melting and coalescence of Au nanoparticles were investigated using molecular dynamics simulation. The melting points of nanoparticles were calculated by studyin…
Computationally efficient phase-field studies combining simulation sampling and statistical analysis
Christian Schwarze, Reza Darvishi Kamachali, Markus Kühbachb +5
The trade-off between accuracy and computational cost as a function of the size and number of simulation boxes was studied for large-scale phase-field simulations. For this purpose…
Multi-Phase-Field Model for Surface/Phase-Boundary Diffusion
Raphael Schiedung, Reza Darvishi Kamachali, Ingo Steinbach +1
The multi-phase-field approach is generalized to treat capillarity-driven diffusion parallel to the surfaces and phase-boundaries, i.e. the boundaries between a condensed phase and…
