Description	Rapidly solidified particles of high-speed steel were classified into several granulometric fractions ranging from less than 25 mu m up to more than 160 mu m in diameter and studied by transmission and conversion electron Mossbauer spectrometry. The former was applied at 300, 77, and 5 K. Presence of magnetic and a non-magnetic crystallographic phase was observed. They were identified by X-ray diffraction as ferrite (bec-Fe) and austenite (fcc-Fe), respectively. In addition, M4C3 and M2C carbides were found. The magnetic phase diminishes in the bulk of the particles bigger than 63 mu m (transmission Mossbauer spectroscopy) and/or 80 mu m (X-ray diffraction). Its contribution is higher at the surface of the particles (conversion electron Mossbauer spectrometry). The origin of the non-magnetic phase is not changed even at 5 K. Reasonable agreement is achieved between Mossbauer and X-ray diffraction data as far as the fraction of Fe-containing phases is concerned.
