摘要： The invention provides a hot stamped structural component (20) for an automotive vehicle, such as a B-pillar, including a first part (22) formed of a high strength steel material joined to a second part (24) formed of a high ductility steel material. The structural component (20) also includes a locally tempered transition zone (26) along the joint (28) to reduce the potential for failure along the joint (28). The transition zone (26) has strength and ductility levels between the strength and ductility levels of the remaining portions of the first and second parts (22, 24). The tempering step can be incorporated into a laser trimming cell or assembly cell, and thus the transition zone (26) can be created without adding an additional process step or increasing cycle time.
