Nanotwinned Titanium (IMAGE) DOE/Lawrence Berkeley National Laboratory Caption Scientists at Berkeley Lab’s Molecular Foundry used an electron microscopy technique called electron backscatter diffraction (EBSD) to image the structure of pure titanium with a nanotwinned structure. Each color represents a unique orientation of the grains. The thin strips reveal the nanotwinned structure produced through a process called cryo-forging.
