Abstract In the present work, we report the observation of deformation kinking bands in β-treated commercial pure zirconium sheets during impact experiments. Crystallography analyses based on electron backscatter diffraction (EBSD) technique reveal that these kinking bands exhibit a common rotation axis of 〈 10 1 ¯ 0 〉 with misorientation angles varying in a wide range and are not belonging to anyone of the well-established twinning modes in Zr. Based on the combination of Schmid factor calculation and in-grain misorientation axes (IGMA) determination, the underlying mechanisms accounting for their formation are proposed and discussed.

分离式霍普金森压力棒对 β 处理锆的变形扭结

摘要 在目前的工作中，我们报告了在冲击实验中观察到 β 处理的商用纯锆片中的变形扭结带。基于电子背散射衍射 (EBSD) 技术的晶体学分析表明，这些扭结带表现出一个共同的旋转轴< 10 1 ¯ 0 >，取向差角度在很宽的范围内变化，并且不属于锆 基于施密德因子计算和晶粒内取向差轴 (IGMA) 确定的组合，提出并讨论了解释其形成的潜在机制。
