Researchers from AET Integration, Inc. worked on developing welding techniques that mitigated delayed cracking issues when laser welding Advanced High-Strength Steels (AHSS) and 3rd Gen AHSS.| AHSS Guidelines
The Hole Expansion test (HET) quantifies the edge stretching capability of a sheet metal grade having a specific edge condition. Many variables affect hole expansion performance. By understanding the microstructural basis for this performance, steelmakers have been able to create new grades with better edge stretch capability.| AHSS Guidelines
Key materials characteristics for formed parts include strength, thickness, and corrosion protection. Tailored products provide opportunities to place these attributes where they are most needed for part function, and remove weight that does not contribute to part performance.| AHSS Guidelines
Tailored parts are the term given to those parts that may have zones with different thickness, chemistry, or heat treatment, resulting in a reduced number of components, weight reduction, and/or lower costs. These goals are achieved through part consolidation and by reducing or in some cases even eliminating joining operations.| AHSS Guidelines
In its simplest explanation hot stamping consists of five operations: (1) blanking (or cutting-to-length), (2) forming, (3) heating, (4) cooling (quenching) and (5) trimming/piercing. Each process route listed below has a distinct order or type of these operations.| AHSS Guidelines
Researchers from RWTH Aachen University in GermanyR-24 used representative volume elements (RVE) in tandem with electron probe microanalysis and micromechanical finite element (FE) modeling to develop flow curves for 2.5 mm hot rolled DP 600 steel sheet.| AHSS Guidelines

Roll Forming takes a flat sheet or strip and feeds it longitudinally through a mill containing several successive paired roller dies, each of which incrementally bend the strip into the desired final shape. The incremental approach can minimize strain localization and compensate for springback.| AHSS Guidelines
Roll forming is no longer limited to producing simple circular, oval, or rectangular profiles. Advanced cross sections highlight some profile designs that aid in body structure stiffness and packaging space reductions.| AHSS Guidelines
