Nabarro–Herring creep, also known as Nabarro–Herring diffusion creep, is a mechanism of creep deformation that occurs in materials, particularly in polycrystalline metals and ceramics, at elevated temperatures and under constant load. This creep mechanism is named after two scientists, Sir Harold Nabarro and Sir Charles Herring, who independently described the phenomenon.
