PNNL researchers are visualizing how shear forces rearrange metal atoms in ways that translate to improved characteristics – greater strength, ductility, and conductivity – to inform a custom design of next-generation metals with broad applications from batteries to vehicles.

Hoping to gain insights into processes that would create longer-lasting batteries and lighter vehicles, scientists at Pacific Northwest National Laboratory in Washington are investigating the effects of physical forces on metals at the atomic level as they undergo shear deformation.

Shear deformation occurs when an object changes shape when forces are applied to it but not in the way of just be...
