Direct Imaging of Hydrogen-Driven Dislocation and Strain Field Evolution in a Stainless Steel Grain
David Yang, Mujan Seif, Guanze He +9
Hydrogen embrittlement (HE) poses a significant challenge to the durability of materials used in hydrogen production and utilization. Disentangling the competing nanoscale mechanis…
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…
Deformation Localisation in Ion-Irradiated FeCr
Kay Song, Dina Sheyfer, Wenjun Liu +6
Irradiation-induced ductility loss is a major concern facing structural steels in next-generation nuclear reactors. Currently, the mechanisms for this are unclear but crucial to ad…
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…
