METHOD FOR METAL FORMING AND A DEVICE FOR PLASTIC WORKING

摘要

FIELD: metal processing.SUBSTANCE: present group of inventions relates to metal forming and can be used for plastic deformation of austenitic steel. Steel is heated to local temperature determined by a break point, then it is plastically deformed. Local temperature is determined based on the analysis of physical properties and deformation mode. Plastic deformation of steel is performed in a working device using a mold or using pressure of the heating medium.EFFECT: to prevent thinning and ruptures of austenitic steel due to increased ductility.19 cl, 7 dwg, 3 tbl
