Vývoj materiálového modelu u oceli pro automobilový sektor

Abstract

The main goal of this work is to create a material model for 34MnB5 manganese steel. The theoretical part of the thesis primarily describes manganese steels and the main alloying elements , as well as the basic methods of production and processing. The following theoretical sections are devoted to heat treatment, which is an essential part when processing manganese steels , and characterization of basic mechanical testing . The experimental section then describes the Gleeble device, which enabled was used to perform the pressure test s . These results were then plotted into graphs, which were subsequently used to create and optimize the model for this material (based on the real test results )). For a better understandi ng of the property development, a brief microstructure analysis of the samples is also shown in the diploma thesis.
