Abstract
Iron was diffused into aluminium along grain boundaries and studied by Mössbauer spectroscopy. The Mössbauer spectrum of the investigated sample contained one doublet with isomer shift δ=0.360/5/ mm s−1 /relative to α-iron/ and quadrupole splitting Δ=0.84/l/ mm s−1. These results suggest that the iron atoms in the grain boundaries of aluminium have environment very similar to that which is present in amorphous iron /III/ oxides.
