| Description
| - Slitiny bohaté Mg v binárním systému Mg-Ni jsou perspektivními materiály na ukládání vodíku. V této studii byly zkoumány desorpční charakteristiky hydridovaného intermetalika Mg2Ni a hydridované eutektické směsi Mg/Mg2Ni. Struktura experimentálních materiálů během hydridování byla studována pomocí SEM. Byly připraveny tři modifikace (Mg2Ni)Hx (x 4) , které se lišili v poměru dvou nízkoteplotních fází f = LT2/LT1: kde f bylo (i) f > 1, (ii) f 1 a (iii) f <1. Vývoj poměru f při desorpci vodíku byl sledován pomocí XRD. Bylo zjištěno, že mikrozdvojčatěná fáze LT2 není vhodná pro uchovávání vodíku. Difúzní koeficient vodíku v LT2 je asi 20x nižší než v LT1.

- Mg-rich alloys of the binary system Mg-Ni are prospective hydrogen-storage materials. In the present study, desorption characteristics of hydrided Mg2Ni intermetallic and hydrided Mg/Mg2Ni eutectic mixture were investigated. Structure of experimental materials during the hydrogenation was observed by SEM. Three modifications of (Mg2Ni)Hx (x 4) were prepared differing in the ratio of two low-temperature phases f = LT2/LT1: with (i) f > 1, (ii) f 1 and with (iii) f <1. Evolution of the ratio f during hydrogen desorption was checked by XRD. It was found that the micro-twinned phase LT2 is not desirable in hydrogen-storage materials containing Mg2Ni intermetallic. Diffusion coefficient of hydrogen in LT2 is about 20 times lower than in LT1.
