Data: Excellent strength-ductility combination, in the absence of twinning, in a novel single-phase VMnFeCoNi high-entropy alloy
Description
This data set contains the following data: Figure 1- Solvus temperature: This folder contains backscatter electron images of VMnFeCoNi specimens cast, homogenized, cold-worked and annealed between 1000 and 1100 °C for 1 h. File name format is alloy composition_ recrystallization (RX)_temperature of annealing_ duration of annealing. Figure 2- SEM standard state: This folder contains two subfolders relating to electron back scatter diffraction (EBSD) and energy dispersive X-ray spectroscopy (EDX) data of VMnFeCoNi recrystallized at 1080°C, 30 min, labeled EBSD and EDX maps, respectively. EBSD contains the processed inverse pole figure map and the inverse pole figure density texture plot, as well as the raw EBSD scan data in the .ctf format, segmented in two subfolders labelled Plots and Raw ctf data, respectively. EDX maps contains the BSE image and corresponding EDX elemental concentration maps for Co, Fe, Mn, Ni, and V. Figure 3- TEM standard state: This folder contains two subfolders relating to transmission electron microscope (TEM) bright field (BF) and selected area diffraction (SAD) as well as TEM-EDX data of VMnFeCoNi recrystallized at 1080°C, 30 min, labeled BF_SAD and EDX, respectively. BF_SAD contains the BF and corresponding SAD images. EDX maps contains the electron image and corresponding EDX elemental concentration maps for Co, Fe, Mn, Ni, and V. Figure 4- Tensile_data: Tensile data including, engineering stress-strain data for VMnFeCoNi samples deformed to 10 % strain, 25 % strain and failure (homogeneous engineering strain: 60%) at RT. Additional true-stress-strain data and associated work-hardening rates for samples deformed to failure are also included (shared in the .dat format). Naming format: alloy composition_recrystallized (RX)_ annealing temperature_annealing time duration_ serial number if deformed to fracture/strain at which test was interrupted. Figure 5- TEM deformed state: TEM-BF and SAD images of samples deformed to 10% tensile strain, 25 % tensile strain, and to fracture. Figure S1- Sigma confirmation: This folder contains two subfolders relating to EBSD processed and raw data of VMnFeCoNi recrystallized at 1000°C, 1h, labeled Plots and Raw ctf data, respectively. Plots contains the processed inverse pole figure map, phase map, and two example Kikuchi patterns from two different sigma phase particles. The folder Raw ctf data contains the raw EBSD data in the .ctf format. Figure S2- Oxide confirmation: Contains the BSE image showing where the EDX line scan was carried out for the EDX data shown in Figure S2, and associated data in .dat format. Grain_size_BSE: This folder contains the raw BSE images that were used to calculate the grain and crystallite size in equiatomic VMnFeCoNi recrystallized at 1080 °C, 30 min via linear intercept method. Naming format: recrystallized (RX)_ annealing temperature_annealing time duration_ serial number.
