Abstract The technique known as 4D-STEM has recently emerged as a powerful tool for the local characterization of crystalline structures in materials, such as cathode materials for Li-ion batteries or perovskite materials for photovoltaics. However,

Minor addition of zirconium is common in polycrystalline nickel-based superalloys, where it is believed that it segregates at grain boundaries and contributes to increase the creep resistance. However, in superalloys produced by additive manufacturin
