Researchers at Pacific Northwest National Laboratory (PNNL) have developed and successfully tested a novel process-called Friction Stir Dovetailing-that joins thick plates of aluminum to steel. The new process will be used to make lighter-weight military vehicles that are more agile and fuel-efficient.

Drawing on distinguishing capabilities in chemistry, earth sciences and data analytics, PNNL researchers advance scientific discovery and create solutions to the nation's toughest challenges in energy resiliency and national security. Founded in 1965, PNNL is operated by Battelle for the U.S. Department of Energy's Office of Science. The national lab employs about 4,500 professionals and has an annual operating budget of nearly $1 billion.
