## 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
AI-Hf alloys were produced by chill casting and gas atomization. The solid solubility of hafnium in aluminium was extended to 2 wt.% Hf in the sub 45/zm size powders. Precipitation of the L12-AI3Hf phase refined the chill cast grain size from 300 /zm to 5 /~m. The powders were consolidated by extrus
