Abstract

Automobile lightening is a direct and effective measure to realize energy saving and emission reduction. TRB of boron steel has greater application value in automotive lightweight. In this work, the TRB scheme of a down plate of rear stringer with thickness of 1.8 mm, 2.0 mm, 1.6 mm and 1.4 mm was designed, and the weight of the vehicle was reduced by 3 kg. Then the numerical simulation of hot stamping process of this TRB part was carried out, and finally the TRB part was hot stamped. The simulation results indicated that there were no major defects after the forming of the part and the strength and hardness reached the expected values. All the tested hardness values of the hot stamped TRB part were above 480 HV, and all the tested yield strength and tensile strength of the TRB part were above 950 MPa and 1300 MPa, respectively.
