Abstract
The requirements of the automotive industry result in the development of new sheet materials which combine good plasticity to form parts possessive complex geometries as well as high strength properties. One such material is the low-carbon air-hardened steel LH800. Technological processing of such sheets includes deep drawing, cutting, air quenching and welding. The initially annealed ferritic microstructure exhibits an elongation at fracture of about 30%. Due to air quenching, the tensile strength can be increased up to 1000 MPa. However, its implementation for chassis elements is limited owing to the distortion caused by the processing treatments mentioned above. To evaluate the distortion caused by air quenching, investigations by means of axially-symmetric deep drawn cups and its sectors were carried out. The geometry of the selected parts before and after air quenching was optically measured. The distortion was analyzed and quantified at various positions on the parts. Moreover, a mathematical model was developed and implemented into the finite-elements software ABAQUS to simulate the distortion of sheet metal products caused by thermal treatment.
