Microstructure data from "Re-Assessing the Strength and Deformation Behavior of B2-ordered Binary Iron Aluminides"

The following file deisgnations are used:

Fe30Al = alloy with nominal 30 at.% Al and 70 at.% Fe
Fe35Al = alloy with nominal 35 at.% Al and 65 at.% Fe
Fe42Al = alloy with nominal 42 at.% Al and 58 at.% Fe
Fe47Al = alloy with nominal 47 at.% Al and 53 at.% Fe
Fe50Al = alloy with nominal 50 at.% Al and 50 at.% Fe
Fe53Al = alloy with nominal 53 at.% Al and 47 at.% Fe

RT = Testing temperature was room temperature (20°C)
400C = Testing temperature was 400°C
500C = Testing temperature was 500°C
600C = Testing temperature was 600°C
700C = Testing temperature was 700°C

Files without temperature designation are micrographs obtained on the initial microstructure.

BSE = Scanning electron microscopy (SEM) images were taken in backscattered electron (BSE) mode at 20kV acceleration voltage
EBSD = Scanning electron microscopy (SEM) analysis using electron backscatter diffraction (EBSD) as angular file exported from the proprietary OIM analysis software

100x or 1000x = Magnification in SEM

CD_hor = compression direction is horizontal
