Unexpected Planar Dislocation Boundary Formation in FCC Metals Captured by Dark-Field X-ray Microscopy and Continuum Dislocation Dynamics
Adam André William Cretton, Khaled SharafEldin, Axel Henningsson +8
Validating dislocation patterning models against in situ imaging experiments is a longstanding goal in materials physics. Here, we provide the first direct morphological comparison…
A general statistical framework for vacancy and self-interstitial properties in concentrated multicomponent solids
Jacob Jeffries, Hyunsoo Lee, Anter El-Azab +1
A rigorous understanding of the thermodynamic properties of point defects, namely vacancies and self-interstitials, is crucial for the discovery and screening of structural materia…
Strain effects on the binding and diffusion energies of Au adatoms and CeO2 admolcules on Au, CeO2, MgO and SrTiO3 surfaces
Ahmad Ahmad, Ying-Cheng Chen, Jie Peng +1
First-principles density functional theory (DFT) calculations were used to study the effects of elastic strains on the binding and diffusion activation energies of Au adatom and Ce…
Dependence of Radiation Induced Segregation of Cr on Sink Dimensionality and Morphology in Fe-Cr Alloys
Mohammadhossein Nahavandian, Anter El-Azab, Enrique Martinez
Radiation-induced segregation (RIS) and chemical redistribution in structural alloys can significantly degrade material performance, ultimately leading to failure. In this study, b…
A first-principles investigation of the diffusivities of oxygen and oxygen defects in ThO
Maniesha Singh, Anter El-Azab
A comprehensive analysis is presented for the diffusivity of oxygen defects and oxygen self-diffusion in ThO. The migration energy and diffusivity of oxygen defects with nomina…
Towards Interfacing Dark-Field X-ray Microscopy to Dislocation Dynamics Modeling
Axel Henningsson, Sina Borgi, Grethe Winther +2
Deformation gradient tensor fields are reconstructed in three dimensions (mapping all 9 tensor components) using synthetic Dark-Field X-ray Microscopy data. Owing to the unique pro…
Effect of electron-phonon coupling on thermal transport in metals: a Monte Carlo approach for solving the coupled electron-phonon Boltzmann transport equations
Jie Peng, W. Ryan Deskins, Maria Helena Braga +1
In this work, the effect of electron-phonon (e-ph) coupling on both electron and phonon transport of metals is investigated via first principles calculations. A Monte-Carlo (MC) ap…
End-to-end Phase Field Model Discovery Combining Experimentation, Crowdsourcing, Simulation and Learning
Md Nasim, Anter El-Azab, Xinghang Zhang +1
The availability of tera-byte scale experiment data calls for AI driven approaches which automatically discover scientific models from data. Nonetheless, significant challenges pre…
A quantitative phase-field model for void evolution in defect supersaturated environments: a novel introduction of defect reaction asymmetry
Sreekar Rayaprolu, Kyle Starkey, Anter El-Azab
Voids develop in crystalline materials under energetic particle irradiation, as in nuclear reactors. Understanding the underlying mechanisms of void nucleation and growth is of utm…
