Researchers say longer-lasting batteries, lighter alloys for more efficient vehicles, and custom designs of next-generation metals are now possible.

Lighter vehicles can travel farther on less energy, hence driving demand for lighter automotive components. High-performance aluminum alloys, such as alloy 7075, are among the lightest and strongest options, but they require energy-intensive production that raises costs and therefore limits their use. Now, researchers from the Pacific Northwest National Laboratory...

Lighter vehicles can travel farther on less energy, driving demand for lighter automotive components. High-performance aluminum alloys, such as alloy 7075, are among the lightest and strongest options, but they require energy-intensive production that raises costs and therefore limits their use.

In a paper published in the Journal of Manufacturing Processes, researchers at Pacific Northwest National Laboratory (PNNL) report that their novel Shear Assisted Processing and Extrusion (ShAPE) technology (earlier post) can extrude aluminum alloy 7075 tubing at speeds up to 12.2 m/min without surface tearing. This is first experimental evidence...

Shear Assisted Processing and Extrusion (ShAPE™) uses considerably less energy and can produce a product at over ten times the rate of conventional extrusion, with no compromise in quality.
