Optimalizace teploty tváření ložiskové oceli 100CrMnSi6-4 za poloohřevu

Original language description

The paper focuses on problems of optimizing the forming temperature of grade 100CrMnSi6-4 bearing steel under partial heating. In order to assess its formability, tensile tests at elevated temperatures ranging from 100 to 800oC were carried out. Tensilediagrams revealed jump changes of mechanical properties in the brittle region under blue heat and in the region of phase transformations. Experimental examination was then concentrated on assessing the plastic deformation capability of the material underpressure at elevated temperatures, by means of the upsetting test. Another goal of the paper consisted in comparing the two experimental methods chosen for establishing the optimum temperatures of forming grade 100CrMnSi6-4 bearing steels at elevated temperatures. To have a complex assessment of the experimental material the structure and phase analyses of the bearing steel were performed in dependence on heating temperature.
