This article presents data regarding the research paper entitled "Hierarchically activated deformation mechanisms to form ultra-fine grain microstructure in carbon containing FeMnCoCr twinning induced plasticity high entropy alloy [1]". In this article we provide supporting data for describing the associated mechanisms in microstructure evolution and grain refinement of a carbon-doped TWIP high-entropy alloy (HEA) during thermomechanical processing. Microstructural characterization before and after deformation was performed using scanning electron microscope (SEM) outfitted with EBSD detector and transmission electron microscopy (TEM) were used for microstructure observation and investigation of nanostructure evolution during deformation. Inverse pole figure (IPF) map, grain boundary map and kernel average misorientation map (KAM) were used for systematic analysis of nanostructural evolution and deformed heterostructure consisting of hierarchical mechanical twinning, shear-banding, microbanding and formation of strain-induced boundaries (SIBs).
本文展示了关于题为《含碳FeMnCoCr孪生诱导塑性高熵合金中形成超细晶粒微观结构的分层激活变形机制》[1]的研究论文的数据。在本文中，我们提供了支持数据，用于描述热机械加工过程中碳掺杂孪生诱导塑性高熵合金（HEA）微观结构演变和晶粒细化的相关机制。使用配备电子背散射衍射（EBSD）探测器的扫描电子显微镜（SEM）对变形前后的微观结构进行表征，并使用透射电子显微镜（TEM）观察微观结构并研究变形过程中的纳米结构演变。利用反极图（IPF）图、晶界图和内核平均取向差图（KAM）对纳米结构演变和由分层机械孪生、剪切带、微带以及应变诱导边界（SIBs）形成的变形异质结构进行系统分析。
