Abstract:Based on the combination of materials science and mechanical engineering, hot press forming process of the vehicle high strength steels was analyzed. The hot forming process included: heating alloys rapidly to austenite microstructures, stamping and cooling timely, maintaining pressure and quenching. The results showed that most of austenite microstructure was changed into uniform martensite by the hot press forming while the samples were heated at 900 degrees C and quenched. The optimal tensile strength and yield strength were up to I 530 MPa and 1 000 MPa, respectively, and the shape deformation reached about 23%. And springback defect did not happen in the samples.
