Effect of deformation changes on mikrostrukture of forming steels

Effect of deformation changes on mikrostrukture of forming steels

Paper in proceedings (conference paper)

Mechanical properties of forming steels (e.g.strength, deformation) change with the rare and time of contact between the piece being formed and the tool. One of the experimental methods that simulate real forming processes is Taylor anvil test. The present paper gives a comparison of deformation changes in test specimens stressed by impact force in dependence on impact velocity with structural changes in a selection of steels currently used in the manufacture of joining parts and mechanical engineering components. Comparing experimental results with the results obtained by the LS DYNA 3D simulation program performs the comparison of deformation changes in dependence on impact velocity.
