The alloys were hydrided using a new, electrochemical process to find the most promising alloy. The electrochemical hydriding process consisted of the electrolysis of a 6-M KOH solution in which the hydrided alloy was the cathode. The structures of both the as-cast and hydrided alloys were investigated by light microscopy, electron microscopy and x-ray diffraction. The hydrogen concentration was measured using glow-discharge spectrometry. It was observed that the structures of all the studied alloys contained a significant volume fraction of disperse eutectic mixtures that represented good paths for the inward hydrogen diffusion. The maximum hydrogen mass concentration of 1.6 % was thus achieved in the Mg-26Ni alloy with an almost purely eutectic structure. In thehypoeutectic and hypereutectic alloys the hydrogen concentrations were lower. The mechanism of the hydriding process is discussed in relation to the observed structural features of the alloys"},{"@xml:lang":"sl","#text":"Raziskano je bilo več litih binarnih Mg-Ni in ternarnih Mg-Ni-Mn (Mn = kovina) zlitin s stališča vezave vodika.

Mikrostruktura je bila preiskana z optičnim in elektronskim mikroskopom in rentgensko difrakcijo. Koncentracija vodika je bila merjena s spektrometrijo tlivne razelektritve. Ugotovljeno je bilo, da vse raziskane zlitine vsebujejo pomembnen volumenski delež dispergiranih evtektičnih zmesi, ki so imele dobro pot za difuzijo vodika navznoter. Največja masna koncentracija vodika 1,6 % je bila dosežena pri zlitini Mg-26Ni s skoraj čisto evtektično mikrostrukturo. V hipo- in hiperevtektičnih zlitinah je bila manjša koncentracija vodika.
