    　View Summary

    To improve fuel economy and crash safety of automobile, Three-Dimensional Hot Bending and Direct Quench (3DQ) Technology, which enables the formation of automotive parts with a tensile strength of 1470MPa or more, has been developed. In this study, fundamental research on new forming method is carried out to expand the forming limits in conventional 3DQ. The deformation in new method is shear mode instead of bending mode in conventional 3DQ.The elementary analysis model has been developed to clarify the effects of forming conditions on load. By preliminary test using small-diameter thin-walled steel tube, main results are as follows. ① It is made clear that wrinkles are suppressed with a small bending radius. ②, High strength products, whose hardness distribution are uniform, are obtained. ③ Laser marking lattice on the surface is measured. The expected shear deformation is obtained. Based on these results, aa new high-rigidity test machine is designed by using the analysis model.
