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…
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…
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…
