This dataset contains the relevant raw data of the submission "Overcoming barriers for high temperature alloys: oxidation and ductility". All files highlighted by "MC" denote data on Cr-37.2Mo and "MSC" on Cr-36.1Mo-3Si (both alloy compositions given in at.%).

Fig1 = Scanning electron grayscale micrographs using backscattered electron contrast as *.tif images

Fig2a = area-specific mass changes (average and uncertainty in mg/cm²) as a function of oxidation time (in h); "800C" denotes 800°C and "1100C" denotes 1100°C; the dataset highlighted by "single_sample" is not averaged but determined on a single specimen

Fig2b = engineering stress-strain curves (in MPa and 1, respectively) for room temperature (= "RT") and 900°C (= "900C")

Fig2c = 1% offset yield strength (in MPa) as a function of testing temperature (in °C)

Fig2d = true work hardening (in MPa) as a function of true stress (in MPa) for room temperature (= "RT") and 900°C (= "900C")
