Combined effects of Nb and B microalloying in molybdenum based ultra low carbon bainitic (ULCB) steels

摘要：

ULCB steels have a great potential for structural as well as automotive applications due to the lean alloying concept and the favorable combination of strength and ductility. These steels are being considered as the material of choice for many advanced applications where yield strength above 500 MPa is required to reduce component weight.Traditionally Mo has been a key alloying element in producing such steels. In order to push the property envelope of ULCB steels it is interesting to combine Mo alloying with the microalloying elements Nb and B. Cross effects between these elements bear synergies that cannot be achieved by single alloying. The paper demonstrates how these synergies can be beneficially used in combination with appropriate processing.
