ULTRA HIGH STRENGTH BODY AND CHASSIS COMPONENTS
20180214924 · 2018-08-02 ·

A structural component for an automotive vehicle formed from a single-piece of steel material and having a closed, complex cross-section with increased strength, for example a strength of greater than 650 MPa, and thus improved performance, is provided. The structural component typically has an elongation of greater than 5%. The structural component is formed by expanding a boron-containing steel material, for example heating or hydroforming a tube of the steel material. The boron-containing steel material expands by least 2% during the forming process and thus achieves the closed, complex cross-section, while also achieving the high strength. In addition, the structural component can be formed with zones of varying thickness, strength, hardness, elongation, and/or other varying properties to achieve the desired performance.

High Speed Blow Forming Process to Shape Aluminum Containers Using 3xxx Alloys with High Recycle Content

Provided herein is a high-speed blow forming process for shaping aluminum containers using 3xxx can body stock alloys with high recycled content, as well as articles made by that process. A process for shaping aluminum containers as described herein includes the sequential steps of blanking out a disk from a sheet of a 3xxx series aluminum alloy; forming a bottle preform by drawing redrawing, ironing and doming the disk, placing the preform into a mold cavity, applying an axial load to the preform; and injecting an inert gas into the interior of the preform with sufficient pressure until the preform expands to fill the mold cavity.

HOT SHEET METAL FORMING BY GAS AND DIRECT QUENCHING
20180127849 · 2018-05-10 ·

A hot forming by gas and direct quenching method and apparatus are disclosed. One method of using the system includes a heating step, a forming step, and a direct quenching step. This method increases the quenching speed and allows common steels with high critical cooling rate to be hot formed and quenched. This method reduces or eliminates the need for a furnace and/or the coating of the workpiece prior to the forming, as well as the removal of the coating after the forming. Furthermore, by using a hot gas containing carbon or nitrogen, the workpiece may be case hardened after the heating, forming and quenching steps.
