Some influences on the mechanical properties of steel

The application of metal-forming processes presupposes certain material properties: Under an acting stress caused by external forces, the material must deform like plastic without undergoing a loss in cohesion. The paper examines various influences on material properties. We want to have the best possible plastic properties of the material. Movement of the dislocations is the basic mechanism of plastic deformation. The external forces cause stress fields which are superimposed on those of the dislocations. If the stresses of the resulting stress fields reach a certain magnitude, the dislocations begin to move.
