Structural Transformations in Copper during High-Speed Deformation upon the Convergence of a Massive Cylindrical Shell under Implosion

The deformation structure in copper that forms upon the convergence of a massive cylindrical shell into a cylinder is studied in this work. The shell in the deformation zone was subjected to high-speed deformation (~10 4 1/s) with large values of true strain ( e varied from 0.8 to 2.0). It is shown...
