Dynamic recrystallization in the shear bands of Fe–Cr–Ni monocrystal: Electron backscatter diffraction characterization

An investigation was carried out into the microstructural evolution of the adiabatic shear bands generated under high-strain rate loading in a Fe–Cr–Ni single crystal. The results show that the distribution in plasticity on both sides of the bands during propagation is inhomogeneous, and recrystallization with an average grain diameter of 0.2 μm may occur. These distortion-free nanograins are believed to form as the result of dynamic recrystallization.
