The microstructural characteristics of rapidly solidified materials were examined in terms of the effect of high velocity on the physical processes that govern microstructure formation. Under rapid solidification conditions, non-equilibrium conditions at the interface and a modified diffusional inst
## Abstract Ductile and microcrystalline thin FeβCrβAl foils with an elevated aluminium content up to 12 wt.β% were produced by a rapid soldification process. Alloys with different compositions were tested in isothermal oxidation experiments (HeβO~2~, p(O~2~) = 133 mbar, T = 1273 K) and in cyclic o
