Upon nitriding ferritic iron-based Fe-Cr-Al alloys (containing 0.25-1.25 at.% Cr and Al) a very hard surface layer develops containing nano-precipitates of alloying element nitrides. The microstructure of the nitrided zone was investigated by X-ray diffraction (XRD) and transmission electron microsc
## Abstract The apparent tensile fracture strains, at which cracking of Ξ±βAl~2~O~3~ scales formed on FeβCrβAlβY alloys during oxidation in 1 atm oxygen at 1200 Β°C occur, have been determined by two methods at room temperature. The values are reproducible and depend on the oxidation time but are wit
