Description	Tato práce se zabývá studiem elektrolyticky připravených Fe-W prášků a jejich ustálených vlastností. Syntetizované Fe-W prášky byly studovány s použitím rentgenové difrakce, termální analýzy, Mössbauerovy spektroskopie a termomagnetických měření. Dochází jen k slabé absorpci vodíku. Po tepelném zpracování při 800 °C se amorfní fáze a fáze alfa-Fe(W) rozpadají na převažující alfa-Fe s přibližně 3 at.% W, doprovázeného W(Fe), lambda-Fe2W, a Fe2+ v oxidických fázích. (cs) This paper concerns the study of Fe-W powders, which were prepared by electrolyzing, and the stabilized properties of them. The synthesized Fe-W powders were studied using X-ray diffraction, thermal analysis, Mössbauer spectroscopy and thermomagnetic measurement. Poor hydrogen absorption occurred. After the heat treatment at 800 °C, the amorphous and alpha-Fe(W) phases were decomposed into the prevailing alpha-Fe with approx. 3 at.% W accompanied by the W(Fe), lambda-Fe2W, and Fe2+ in oxide phases.
