Popis: Hot forming is a method to make products with ultra high strength steels which typically used in automotive sector. 22MnB5 is one of the most typical hot forming steels. In this paper, hot forming process of 22MnB5 steel is simulated by thermo-mechanical coupled FE software Pam-stamp 2011. Through the simulation the temperature distribution and martensite phase fraction of hot forming part can be obtained. Besides, a hot forming experiment was set up. The tensile strength and Vickers hardness of hot samples which take from the hot formed part are measured. The experimental results indicate that the value of Vickers hardness in side wall is higher. The microstructure investigations have shown that the part after hot forming mostly fully martensitic microstructures. The result from simulation show good agreement with experimental results.
