Data compilation on the effect of grain size, temperature, and texture on the strength of a single-phase FCC MnFeNi medium-entropy alloy.

摘要: Abstract This data article presents a compilation of microstructural and mechanical regarding the ternary single-phase FCC MnFeNi medium-entropy alloy (MEA). For analysis, interpretation, comparison to literature values, reader can refer original related research entitled “Effect Temperature Texture on Hall-Petch Strengthening by Grain Annealing Twin Boundaries in Medium-Entropy Alloy”, see Schneider et al. (Metals 9, 2019, 84). The reported here include: (i) raw backscatter electron (BSE) micrographs (tif-files) obtained using scanning microscope (SEM) for nine different grain sizes with four images each size (ii) pdf reports tables shown below presenting distributions grain- (d, accounting boundaries only) crystallite- (c, which accounts both annealing twin boundaries) thicknesses (t). These datasets may be useful develop new algorithms automated evaluation parameters recrystallized alloys, i.e. these benchmark data, an algorithm image analysis could trained assess above mentioned parameters. would help speed up microstructures improve its reliability. Additional describing texture include average number per (n), Taylor factors (M). Raeisinia (Model. Simul. Mater. Sc. 16, 2008, 025001) recently used viscoplastic model show that differences distribution affect parameters, but no attempt has been carried out so far experimentally investigate this possibility since are rarely reported. Here, our (e.g. grain/crystallite sizes, twins grain, thicknesses) address issues. properties excel-sheets stress-strain curves temperatures ranging from 77 K 873 sizes. yield stress (σ0.2%) normalized (σ0/G ky/Gb2) given all temperatures. they allow better compare strength magnitude boundary strengthening alloys same crystallographic structure, Cordero (Int.
