High-strength member for vehicle |
摘要 |
A high-strength steel sheet having high strength and ability to absorb impact energy to a high degree is formed into a strengthening member for an vehicle, having both superior energy absorption efficiency and bonding properties. The high-strength member has a high-strength steel sheet having not less than 5000 MPa of gradient du/de of a stress-strain diagram in a range of 3 to 7% of true strain obtained in a tension test, and a steel sheet having 0.3 to 0.85 of tension strength ratio against tension strength of the high-strength steel sheet, the steel sheets bonded at their ends with space extending in a prescribed direction between the steel sheets, and a load is to be applied on the member from the prescribed direction when the member is acted upon. |
