Scientists conducted compression tests of copper specimens irradiated with high-energy protons, designed to model how damage from radiation affects the mechanical properties of copper. By using a specialized in situ mechanical testing device in a transmission electron microscope at the National Center for Electron Microscopy, the team could examine — with nanoscale resolution — the localized nature of this deformation. | Courtesy of Lawrence Berkeley National Laboratory
Researchers Devise New Stress Test for Irradiated Materials

How do you tell if materials are stressed-out? Conventional stress tests for irradiated materials require a significant amount of material, but a new nano-size technique can test the strength of materials using an infinitesimal amount. Learn more.
