Here, we present the results of the synthesis of a complex hydride previously described as Mg2(Fe, Cr, Ni)Hx formed during the reactive ball milling process of AISI 316 L stainless steel (316 L SS) and magnesium hydride under hydrogen pressure. The evolution of powder morphology and phase composition with milling time is presented. The reaction of magnesium hydride with 316 L steel was found to proceed faster than in case of the reaction of reference mixture containing pure iron. Obtained material was found to possess cubic K2PtCl6-structure with slightly different lattice parameter as compared to Mg2FeH6. The hydrogen content of the obtained samples was found to be around 4 wt%. The mixture that resulted from the decomposition of this synthesized sample was able to absorb around 1% of hydrogen even at ? 50 ℃ via the formation of magnesium hydride.
