Convergent-Beam Electron Diffraction pattern in CrMnFeNi high entropy alloy
The diffraction of high energy focused electrons from planes of periodic arrangements of atoms results in disk patterns such as this one. These patterns can be observed in transmission electron microscopes operating at 200,000 Volts on nano-sized samples. This sample is a high-entropy alloy of Cr, Mn, Fe, and Ni. This alloy has been investigated for applications to nuclear fusion.
