Mapping strain rate dependence of dislocation-defect ...Defects in crystalline lattices cause modulation of the atomic density, and this leads to variations in the associated electrostatics at the nanoscale. Mapping these spatially varying charge fluctuations using transmission electron microscopy has typically been challenging due to complicated contrast transfer inherent to conventional phase contrast …Strain rate affects the dislocation interactions and plasticity in materials. Quantitative prediction of dislocation–defect interaction mechanisms and critical stresses as a function of strain rate, reaching down to the experimental deformation conditions much lower than 10 6 s –1, has been an outstanding challenge to traditional atomistic ...The acquired raw data are treated to obtain a 3D (qr, qη, qω) reciprocal space map of a 400 diffraction peak of a grain having one of its <100> directions close to the printing direction (Eq. (A ...Google Arts & Culture features content from over 2,000 leading museums and archives, which have partnered with the Google Cultural Institute to bring the world's treasures online.
