Energy evolution in nanocrystalline iron driven by collision cascades
Ivan Tolkachev, Daniel R. Mason, Max Boleininger +2
Nanocrystalline materials are promising candidates for future fusion reactor applications, due to their high density of grain boundaries which may serve as sinks for irradiation in…
Atomistic simulations of irradiation damage on the engineering timescale: Examining the dose rate effect in tungsten
Max Boleininger, Daniel R. Mason, Thomas Schwarz-Selinger +1
The change in materials properties subjected to irradiation by highly energetic particles strongly depends on the irradiation dose rate. Atomistic simulations can in principle be u…
Atomistic and experimental study of microstructural evolution in nanocrystalline iron subjected to irradiation
Ivan Tolkachev, Daniel R. Mason, Max Boleininger +6
Nanocrystalline materials have been proposed for use in future fusion reactors due to their high grain boundary density that may act as a sink for irradiation-induced defects. We u…
Atomistic simulations of athermal irradiation creep and swelling of copper and tungsten in the high dose limit
Luca Reali, Max Boleininger, Daniel R. Mason +1
Radiation creep and swelling are irreversible deformation phenomena occurring in materials irradiated even at low temperatures. On the microscopic scale, energetic particles initia…
Simulated TEM imaging of a heavily irradiated metal
D. R. Mason, M. Boleininger, J. Haley +4
We recast the Howie-Whelan equations for generating simulated transmission electron microscope (TEM) images, replacing the dependence on local atomic displacements with atomic posi…
Fast low-temperature irradiation creep driven by athermal defect dynamics
Alexander Feichtmayer, Max Boleininger, Johann Riesch +7
The occurrence of high stress concentrations in reactor components is a still intractable phenomenon encountered in fusion reactor design. We observe and quantitatively model a non…
Atomistic Study of Irradiation-Induced Plastic and Lattice Strain in Tungsten
Jintong Wu, Daniel R. Mason, Fredric Granberg
We demonstrate a practical way to perform decomposition of the elasto-plastic deformation directly from atomistic simulation snapshots. Through molecular dynamics simulations on a…
Simulations of Nanocrystalline Iron Formation under High Shear Strain
Ivan Tolkachev, Pui-Wai Ma, Daniel Mason +1
High-shear methods have long been used in experiments to refine grain structures in metals, yet the underlying mechanisms remain elusive. We demonstrate a refinement process using…
Observation of transient and asymptotic driven structural states of tungsten exposed to irradiation
Daniel R. Mason, Suchandrima Das, Peter M. Derlet +8
Combining spatially resolved X-ray Laue diffraction with atomic-scale simulations, we observe how ion-irradiated tungsten undergoes a series of non-linear structural transformation…
Atomistic-Object Kinetic Monte Carlo simulations of irradiation damage in tungsten
Daniel R. Mason, Andrea E. Sand, Sergei L. Dudarev
We describe the development of a new object kinetic Monte Carlo code where the elementary defect objects are off-lattice atomistic configurations. Atomic-level transitions are used…
