On the characterization of bulk copper produced by cold gas dynamic spray processing in as fabricated and annealed conditions

Design and development of copper coatings for long term storage of used nuclear fuel

“…As expected, 12 as deposited samples have very little ductility; generally 1-2% elongation at fracture was observed for samples within the NWMO program, as measured in standard tensile testing via ASTM-E8. 13 Preliminary results indicate that annealing at 600uC achieves ductility comparable to wrought copper; optimisation of this heat treatment cycle is underway.…”

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

“…However, as produced, the resultant Cu coating is expected to have significant residual cold work, with additional hardness and a low fracture toughness. These properties can be altered to produce a more conventional form of Cu by post-deposition annealing at moderately low temperatures (i.e., 300e400 C) [19].…”

Pressureless sintering of cold sprayed Inconel 718 deposit

“…In addition to coating applications, CS was found to be attractive for building protrusions on substrates [3] and even for joining materials [4]. The scientific literature tends to agree that jetting and adiabatic shear at the particle boundaries is responsible for the establishment of the interparticle metallurgical bonds [5].…”
