Dynamics and extreme plasticity of metallic microparticles in supersonic collisions

Abstract Metallic microparticles can acquire remarkable nanoscale morphologies after experiencing high velocity collisions, but materials science regarding the extreme events has been limited due to a lack of controlled experiments. In this work, collision dynamics and nonlinear material characteris...
