摘要：

The micro alloyed steels proved to be reliable materials for the forged automotive parts because of their high strength in as normalized condition. However their use is limited at parts non subjected to impact because the toughness of such a material is relatively low. In order to improve the mechanical characteristics, deformability, strength and toughness, researches focused on the micro alloying content (especially Nb and V) and on processing parameters. The present research aimed at obtaining new micro alloyed steels having improved toughness in as forged/normalized condition. The influence of the chemical composition (Nb/Ti ratio) and of forging parameters as cooling speed and reduction degree were analyzed. For given amounts and ratio of V and Nb, very good mechanical and structural properties were obtained. The tests have been performed on forged parts and bars. (C) 2017 Elsevier Ltd.
