Abstract
© 2020 Author(s). Metallic bonding of certain materials can be achieved via high-velocity impact, and this type of bonding is often linked to an intense extrusion of material from the impact site, known as jetting. We present in situ observations of hydrodynamic jetting and ejection of matter from high-velocity metallic microparticle impacts that still result in rebound of the particle. While the occurrence of jetting has been linked to permanent particle deposition in prior studies, the present findings reveal that any bonds that may form upon jetting can be rebroken by particle rebound in some circumstances. We further present asymmetric occurrences of jetting associated with localized delays in particle detachment followed by rotation during particle rebound, which may speak to transient bond formation at the jetting sites.
