Computational Design of Ductile Additively Manufactured Tungsten-Based Refractory Alloys
Kareem Abdelmaqsoud, Daniel Sinclair, Venkata Satya Surya Amaranth Karra +4
Tungsten exhibits exceptional temperature and radiation resistance, making it well-suited for applications in extreme environments such as nuclear fusion reactors. Additive manufac…
Computational statistics of segregation and dislocation activities of hydrogen charged free surfaces and grain boundaries
Matthew J. Melfi, S. Mohadeseh Taheri-Mousavi
Revealing statistics of H-defect interactions provides insights into significant ductility loss due to the particular strain partitioning in H-charged structural alloys. Experiment…
Laser-scanning of induction-melted Al alloys: are they representative of additively manufactured ones?
Zhaoxuan Ge, Sebastian Calderon, S. Mohadeseh Taheri-Mousavi
The bottleneck of alloy design for powder-based additive manufacturing (AM) resides in customized powder production - an expensive and time-consuming process hindering the rapid cl…
On-lattice voxelated convolutional neural networks for prediction of phase diagrams and diffusion barriers in cubic alloys
Seyedeh Mohadeseh Taheri-Mousavi, Seyed Sina Moeini-Ardakani, Ryan W. Penny +2
Cluster expansion approximates an on-lattice potential with polynomial regression. We show that using a convolutional neural network (CNN) instead leads to more accurate prediction…
On stress concentration in nanotwinned metals
Seyedeh Mohadeseh Taheri-Mousavi, Huajian Gao
In their papers, Lu et al. analysed experimental data from in-situ transmission electron microscopy (TEM) and concluded that local stress concentration at grain boundary-twin bound…
Highly efficient parallel grand canonical simulations of interstitial-driven deformation-diffusion processes
Seyed Sina Moeini-Ardakani, Seyedeh Mohadeseh Taheri-Mousavi, Ju Li
Diffusion of interstitial alloying elements like H, O, C, and N in metals and their continuous relocation and interactions with their microstructures have crucial influences on met…
