Abstract

Pure intermetallic phases Al13Fe4, Al6Fe, AlmFe and AlxFe have been extracted from Bridgman grown model aluminium–iron binary alloys by dissolving the aluminium matrix in butanol. Each phase has a distinct Mössbauer spectrum and variable temperature 57Fe Mössbauer studies have enabled the Debye temperature \(\theta _D \) of each phase to be determined. Hence, the variation of the recoil‐free fraction f with temperature is determined for each phase. From this information it is possible to measure the proportion of each phase, either when the phases are extracted or in situ in aluminium. The results obtained can be used in the characterisation of industrially cast aluminium.
