Abstract
Hot stamping is the most efficient manufacturing process to produce high strength automotive parts with reduced springback. Recently, 30MnB5 steel has been developed for hot stamping steel which can provide above 1700 MPa. However, resistance spot weldability of this steel is insufficient due to the need for a large amount..... More

Korean J. Met. Mater. 2019;57(11):708-714.   Published online 2019 Oct 8
DOI: https://doi.org/10.3365/KJMM.2019.57.11.708

Abstract
Resistance Element Welding (REW) is a novel processing technology developed to join dissimilar materials such as aluminum and steel. It uses an auxiliary steel rivet (element) inserted into an aluminum sheet that forms a resistance spot weld with the steel sheet, and the aluminum work piece is mechanically joined by.....

Korean J. Met. Mater. 2019;57(3):193-201.   Published online 2019 Feb 8
DOI: https://doi.org/10.3365/KJMM.2019.57.3.193

Abstract
The hot stamping process is beneficial for fabricating high strength automotive parts without spring back. To suppress high temperature oxidation and decarburization, it is necessary to coat the hot stamping steel. In the present work, the performance of galvannealed coated (GA) hot stamped steel was evaluated. During cyclic corrosion tests,..... More
