Abstract Al0.1CoCrFeNi high-entropy alloys are firstly processed by cyclic dynamic torsion (DT) using Split-Hopkinson Torsional Bar. Gradient hierarchical microstructures produced by DT are investigated using electron backscattered diffraction, transmission electron microscopy, and nanoindentation tests. Based on the gradient torsional strain, significant grain refinement, remarkable work hardening, and hierarchical deformation substructures are introduced into the current DT-HEAs.

Al0.1CoCrFeNi高熵合金动态扭转的梯度分级晶粒结构

摘要 首次使用Split-Hopkinson 扭杆通过循环动态扭转(DT) 加工Al0.1CoCrFeNi 高熵合金。使用电子背散射衍射、透射电子显微镜和纳米压痕测试研究了由 DT 产生的梯度分层微结构。基于梯度扭转应变，将显着的晶粒细化、显着的加工硬化和分层变形子结构引入当前的 DT-HEAs 中。
