Characterization of commercially cold sprayed copper coatings and determination of the effects of impacting copper powder velocities

“…While further investigations are required to define the recrystallization mechanism, there are many features within the grains formed at lower spraying velocities that have been reported to contribute and favour effective recrystallization. These include grain boundary anisotropy and curvature, and extensive sub-grain networks that would favourably coarsen into larger grains during annealing [43,44]. Fig.…”
