Grain boundary metastability controls irradiation resistance in nanocrystalline metals
Osman El-Atwani, Annie K. Barnett, Enrique Martinez +13
Grain boundaries (GBs) in polycrystalline materials are powerful sinks for irradiation defects. While standard theories assume that the sink efficiency of a grain boundary is defin…
Stochastic Integration of the Cahn-Hilliard Phase Field Equations
Qianran Yu, Nicholas Julian, Jaime Marian +1
In this work we develop a stochastic algorithm to integrate the Cahn-Hilliard equations. The algorithm is based on Gillespie's stochastic simulation algorithm, also known as kineti…
A phenomenological dislocation mobility law for bcc metals
Giacomo Po, Yinan Cui, David Rivera +4
Dislocation motion in body centered cubic (bcc) metals displays a number of specific features that result in a strong temperature dependence of the flow stress, and in shear deform…
The atomistic representation of first strain-gradient elastic tensors
Nikhil Chandra Admal, Jaime Marian, Giacomo Po
We derive the atomistic representations of the elastic tensors appearing in the linearized theory of first strain-gradient elasticity for an arbitrary multi-lattice. In addition to…
Thermally-activated Non-Schmid Glide of Screw Dislocations in W using Atomistically-informed Kinetic Monte Carlo Simulations
Alexander Stukowski, David Cereceda, Thomas D. Swinburne +1
Thermally-activated $\small{\nicefrac{1}{2}}<111>$ screw dislocation motion is the controlling plastic mechanism at low temperatures in body-centered cubic (bcc) crystals. Motion p…
