Using atomistic simulations and dislocation theory on a model system of semi-coherent {111} interfaces, it is shown that misfit dislocation nodes adopt multiple atomic arrangements corresponding to the creation and redistribution of excess volume at the nodes. Four distinctive node structures were identified: volume-smeared nodes with (i) spiral or (ii) straight dislocation patterns, and volume-condensed...
A novel interface engineering strategy is proposed to simultaneously achieve superior irradiation tolerance, high strength, and high thermal stability in bulk nanolayered composites of a model face‐centered‐cubic (Cu)/body‐centered‐cubic (Nb) system. By synthesizing bulk nanolayered Cu‐Nb composites containing interfaces with controlled sink efficiencies, a novel material is designed in which nearly...
