By optimizing the hot water temperature and treatment time to achieve peak complexity in the nanoscale structuring, the team was able to significantly increase the tensile-shear strength compared with untreated metal. “Our process can be adapted for a wide range of hybrid joining applications, in whichmetal and plastic parts need to be permanently bonded,” says lead researcher Yusuke Kajihara. “Furthermore, our method does not use harsh chemicals or complicated procedures and thus is suited to the scale-up required for industrial application.” www.u-tokyo.ac.jp/en. MAKING MORE SUSTAINABLE ALUMINUM ALLOYS Constellium SE, Paris, will lead a new consortium of European automakers and suppliers to develop lower carbon, lower cost aluminum extrusion alloys. Sponsored by a grant from the U.K.’s Advanced Propulsion Center, the $12 million CirConAl (Circular and Constant Aluminium) project aims to maximize the use of post-consumer scrap in a new generation of highstrength alloys that emit less than two tons of CO2 per ton of aluminum produced. CirConAl is part of joint government and industry support for projects to build an end-to-end supply chain for zero-emissions vehicles in the U.K. By designing, developing, proto- typing, and testing aluminum automotive components at scale, the project is expected to demonstrate that high-strength alloys with high recycled content can meet or exceed OEM requirements, such as strength, crushability, durability, and other performance criteria. constellium.com. The consortiumwill develop scrap sorting technologies to ensure that valuable metal is recycled into new automotive solutions rather than downcycled. Courtesy of Constellium.
