Analysis of the impact wave influence on the structure of material in the process of shaping material by explosion

Using explosive as a source of energy in the process of shaping tin-sheet is possible in volume shaping process as well as in other processes of tin-sheet shaping, e.g. making holes, calibration, surface hardening, etc. In this case, a 200-mm bottom made of Č 4580 was being shaped, and the structure of material was examined as well. Speed of detonation was 2994 m/s and 6105 m/s. Explosive used in this case was Vitezit 20, and the medium for transmission of energy was water. Mentioned steel, before it was being shaped, had austenite structure and it belongs to non-magnetic steels, it cannot be tempered, it is hard to be shaped by cutting, but it is good to be drawn.

speed of deformation; water as a medium for transmission of energy; austenite structure.
