Data from "A novel synthesis pathway for oxide dispersion strengthened Fe–Cr alloys enabled by ultrasonic atomization"

Desired composition of the alloy under investigation: Fe-14Cr-0.4Ti-0.5Y (in wt.%) / Fe-15Cr-0.5-0.3Y (at.%). AA = as-atomized powder (ultrasonic atomization) HT = heat-treated powder (1100 °C/1 h) FAST = field assisted sintered (1130 °C/5 min/24 kN) Fig 1a: scanning electron micrographs, backscattered electron contrast; cross section of the "Bottom" and "top" part of a cast rod Fig 1b: scanning electron microscopy - energy dispersive X-ray spectroscopy maps of a representative region Fig 1c: scanning electron microscopy - electron backscatter diffraction pattern, plain and with indexing according to ThMn12 prototype pattern Fig 2: scanning electron micrographs, secondary electron contrast and backscattered electron contrast; topography of powder particles and cross sections (AA and HT) Fig 3: atom probe tomography datasets in the proprietary data format by Cameca (IVAS software version 3.6.14) as well as 1D concentration profiles Fig 4: scanning electron micrographs, backscattered electron contrast; cross sections of FAST material Fig 5: O and Y content as a function of processing condition by carrier gas hot extraction and inductively coupled plasma optical emission spectrometry Table 3: scanning electron micrographs, backscattered electron contrast; cross sections Fig S1: scanning electron micrographs, secondary electron contrast and backscattered electron contrast; topography of powder particles and cross sections Fig S2: X-ray diffraction patterns as intensity in 1 vs. 2theta angle in ° Fig S3: atom probe tomography datasets in the proprietary data format by Cameca (IVAS software version 3.6.14) Fig S4: scanning electron micrograph, backscattered electron contrast; cross section Fig S5: transmission electron micrograph (bright field) and selected area diffraction pattern Further details are found in the preprint linked to this dataset. -------- We gratefully acknowledge financial support from the Deutsche Forschungsgemeinschaft (DFG), project no. 462420328.
