摘要: Pure copper was deformed at ultra-high strain-rates by the technique of cold spraying. It found that after annealing hardness samples does not fall as low is known for heavily normal strain rates, e.g., rolling. The reason this presence defects do heal out 600 °C. These were identified dislocation loops extrinsic and intrinsic kind. Possible mechanisms formation these are discussed.
