Method of Production of High-Strength hollow Bodies from Multiphase Martensitic Steels

Popis výsledku v původním jazyce

The method of production of high-strength hollow bodies from multiphase martensitic steels includes a heating process, a forming process and a cooling process. The device for heating is used to heat the hollow steel stock to the austenitic temperature ofthe material from which the stock is made. Then, the stock is converted by means of deformation in the forming device into a hollow body having the final shape. Immediately thereafter, the hollow body having the final shape is cooled in the cooling device in such a way that the material with the original austenite microstructure refined by deformation introduced during the forming process is cooled down to a temperature, at which incomplete transformation of austenite to martensite takes place. Immediately thereafter the retained austenite stabilization is performed in the annealing device by diffusion-based carbon partitioning within the material from which the hollow body is made. Once the stabilization is finished, the hollow body i
