Abstract
57Fe Mössbauer spectroscopy and electron microprobe analysis are used to determine the Al-distribution in the Nd-Fe-Al-B alloys ; Mössbauer spectroscopy gives the Al distribution between the J2 and K2 sites of Nd2Fe14B-like-phase ; microprobe analysis gives the composition of both matrix and minor phases and their evolution with sintering.
