A Heavyweight Solution for Lighter-weight Combat Vehicles
New technique developed by PNNL successfully joins thicker aluminum alloys to steel
Discovering Stronger Steel for Less Dam-age
A PNNL study that evaluated the use of friction stir technology on stainless steel has shown that the steel resists erosion more than three times that of its unprocessed counterpart.
Research in Tri-Cities Could Make Cars and Planes More Fuel Efficient and Super Strong
Superman may be known as the "Man of Steel," but scientific superheroes at the Department of Energy's Pacific Northwest National Laboratory are developing a novel approach for manufacturing metals with superior strength.
Innovative Energy Technologies Move Closer to Commercial Use
Twelve energy-related technologies developed at PNNL have been selected for additional technology maturation funding to help move them from the laboratory and field tests to the marketplace.
Riveting Technology Enables Lightweight Magnesium Fasteners for Fuel Efficiency
Rotational Hammer Riveting, developed by PNNL, joins dissimilar materials quickly without preheating rivets. The friction-based riveting enables use of lightweight magnesium rivets and also works on aluminum and speeds manufacturing.
Friction Stir Processing Gets a Boost from New Machine Learning Model
PNNL researchers have developed a new, physics-informed machine learning model that accurately predicts how heat accumulates and dissipates during friction stir processing.
