Electropulse‐Driven Dislocation Evolution in Sub‐10 nm Metallic Nanocrystals

open access: yesAdvanced Science, EarlyView.
Atomic‐scale TEM imaging reveals how nanosecond electropulses drive dislocation evolution in sub‐10 nm metallic nanocrystals. Enhanced electron scattering at structural heterogeneities nucleates dislocation loops and dipoles, which then repeatedly interact and annihilate, causing dislocation density fluctuations or structural disordering.

Impact Welding in a Variety of Geometric Configurations

open access: yes, 2010
Magnetic pulse welding is an electromagnetically assisted high strain rate impact welding technology. The physical principle is similar to explosive welding and it also belongs to solid state impact welding. This high velocity oblique impact welding has been applied to various lap joint configurations.
