Abstract: . The article is devoted to the study of the features of dynamic deformation and destruction of porous iron under the influence of a cumulative “knife”. It is shown that ultrafast action on the target led to intensive structure formation of porous iron at the mesoscale.

Keywords: structure, super-fast impact, martensite, dendrites.
