| Description
| - Byly pozorovány strukturní změny během hydrogenace čistého Mg, intermetalika Mg2Ni (I) a Mg eutektické slitiny 23,5 hm.% Ni (E). Vzorky byly připraveny (i) kulovým mletím a kompaktováním (slitiny I a E) a (ii) odlitím do formy (Mg a slitina E). Fázové složení bylo zkoumáno pomocí SEM a XRD. Bylo zjištěno, že navodíkovaná odlitá slitina I a slitina I připravená kulovým mletí navodíkované pod přechodovou teplotou Ttr = 508 K obsahují mnohem větší podíl nízkoteplotní nedvojčaté fáze LT1 než slitina I připravená kulovým mletí navodíkovaná nad Ttr. Bylo ukázáno, že mikrodvojčatá fáze LT2 snižuje rychlost desorpce vodíku. Trvalé změny morfologie byly pozorovány ve všech materiálech po první cyklu vodíkování, což může být vysvětleno tak zvanou aktivací slitin na bázi Mg pro ukládání vodíku popsanou v literatuře. (cs)
- Structure changes during hydrogenation are observed in pure Mg, Mg2Ni intermetallic (I) and Mg eutectic alloy - 23.5 wt.% Ni (E). Samples were prepared by (i) ball-milling and compacting alloys (alloys I and E) and (ii) by mould casting (Mg and alloy E). Phase composition was checked by SEM and XRD. It was found that the hydrogenated cast alloy I and ball-milled alloy I hydrogenated below transition temperature Ttr = 508 K contained a much higher amount of low-temperature un-twinned phase LT1 than the ball-milled alloy I hydrogenated above Ttr. It was shown that micro-twinned phase LT2 slows down the rate of hydrogen desorption. Persistent changes of morphology were observed in all materials after the first hydrogen charging cycle which may explain the so-called activation of Mg-basedd hydrogen-storage materials described in the literature.
