A procedure with your device to increase the limit of elasticity, the limit of stretching and, eventually, the resistance to the breakage of steel material. (Machine-translation by Google Translate, not legally binding)

摘要

A method with its device for increasing the yield strength, the drafting limit and, if applicable, the breaking strength of steel material, preferably in the form of bars, wire or strip, by cold deformation, characterized in that the material is put into a state of creep by forces of a first class of deformation, favorable with respect to the consumption of force, being exposed in this state to the forces of a second kind of deformation, which give the material the degree of deformation required for the desired increase of the yield strength, of the drawing limit or of the breaking strength.
