Abstract. Automotive structural components from Advanced High Strength Steels (AHSS) can be manufactured with Flexible Roll Forming (FRF). Flange wrinkling is a common shape defect in FRF, this restricts the application of FRF automotive industry. The new Incremental Shape Rolling process (ISR) showed that high tensile transverse strain developed flange and assists plastic deformation flange. H...

Joints of complex phase 780 (CP-780) advanced high strength steel (AHSS) were carried out by using an ER-CuAl-A2 filler metal for the gas arc welding pulsed brazing (GMAW-P- brazing) process and ER-80S-D2 GMAW-P employing two levels heat input. The phases in weld bead HAZ analyzed, evaporation zinc means scanning electron microscopy (SEM) was also monitored. mechanical properties welded joints ...

Abstract Driven by current safety and weight reduction policies in the automotive sector, development of new high strength sheet metal products has experienced unprecedented growth last years. With emergence these materials, challenges related to their limited ductility higher cracking susceptibility have also raised. Accordingly, fracture criteria accounting for material’s resistance become un...

Abstract Double-sided friction stir welding (FSW), performed with a pair of rotation tools, was studied in an attempt to increase the joining speed when applied automotive advanced high-strength steels (AHSS). The experiments were on butt joint 1.6-mm-thick 1180 MPa grade steel sheets, and sound welds obtained travel no more than 4 m/min, fairly comparable laser beam (LBW), one conventional pro...
