摘要：
Discontinuous dynamic recrystallization can occur during dynamic tensile extrusion of copper, which is subjected to uniaxial tensile strains of ~5 and strain rates up to 106 s−1 in the extruded section. Through high-resolution transmission Kikuchi diffraction, we show that nucleation occurs through subgrain rotation and grain boundary bulging at boundaries between 〈001〉 and 〈111〉 oriented grains. The observed nuclei consist of subgrains with a size of approximately 200 to 400 nm.
