Deformation behavior of copper upon loading by spherically converging shock waves: Low-intensity loading conditions

X-ray diffraction, optical metallography, transmission electron microscopy, and microhardness measurements were used to perform a layer-by-layer study of the structure of a copper sphere 70 mm in diameter after loading by spherically converging shock waves. It has been found that the high-rate plast...

Description
Summary:X-ray diffraction, optical metallography, transmission electron microscopy, and microhardness measurements were used to perform a layer-by-layer study of the structure of a copper sphere 70 mm in diameter after loading by spherically converging shock waves. It has been found that the high-rate plastic deformation of copper proceeds mostly by slipping, rather than twinning under the used loading conditions. Shear bands are observed at the macrolevel, while a homogeneous dislocation structure, microbands, and microtwins are observed at the microlevel.
