Maximum plastic strengthening in tool steels

Resumo

A method is proposed for calculating the maximum strengthening in tool steels in plastic shaping. The method is based on the permissible deformational damage of the material. In the proposed approach, the influence of the stress state is taken into account in calculating the plastic strengthening and deformational damage of the material. The relation between the deformational damage and plastic strengthening is studied. The influence of plastic strengthening on the mechanical properties of tool studies is established.
