Dataset for microstructure and mechanical properties of (CrCoNi)97Al1.5Ti1.5 medium entropy alloy twisted by free-end-torsion at room and cryogenic temperatures.


ABSTRACT: This data article presents the torsion parameters and the microstructural data of the (CrCoNi)97Al1.5Ti1.5 medium-entropy alloy (MEA). The data presented in this article are related to the research article entitled "Microstructure and mechanical properties of (CrCoNi)97Al1.5Ti1.5 medium entropy alloy twisted by free-end-torsion at room and cryogenic temperatures", see Ref. [1]. This article can be used for data analysis and interpretation and their comparison with other data sets in the research articles. The microstructure and the element distributions of the as-swaged rods were obtained using a scanning electron microscope (SEM) equipped with electron channelling contrast imaging (ECCI), electron diffraction spectroscopy (EDS) and electron backscattered diffraction (EBSD) detectors. The phases of the MEA before and after torsion are determined by the X-ray diffractometer (XRD) techniques. Optical micrograph, inverse pole figure (IPF) map, grain boundary map and misorientation angle distribution and pole figure of the as-swaged sample were presented. I In order to provide data reference for future torsion experiments, this article draws schematic diagrams of the hot-swaged rod, dimensions of the torsion/tensile specimens, liquid nitrogen (@LN) environment torsion device and schematic representation for characterization locations of microstructure. Lastly, Kernel Average Misorientation (KAM) maps and misorientation angle distribution of various samples or different strained layers were used for comparative analysis.
