Mössbauer effect of Al-Fe-Si intermetallic compounds

Mössbauer spectra were obtained for α and β-Al-Fe-Si intermetallic compounds, which are usually detected as precipitates in commercial grade Al metals. The samples were prepared by two methods, electrolytic extraction of precipitates from Al ingots and direct melting of appropriate amounts of raw materials. By the latter method, pure compounds have been obtained, whose spectra can be used as the standard spectra of these compounds to analyze the Mössbauer spectra of Al alloys.
