Keywords : Fe-Al, Fe-Al-Ni, self-decomposition method, Mössbauer spectroscopy INTRODUCTION Iron aluminides represent an intriguing class of materials; they offer a good combination of mechanical properties, specific weight/strength ratio, corrosion resistance and relatively low raw material cost [1,2], which makes them potential candidates for the substitution of stainless steel in applications at moderate to high temperature.
The classical chemical analysis indicated that aluminium concentration in both materials is above 50 at.%.
