Abstract: Bulk consolidated samples of 2Mg–Fe were produced by hot extrusion and by hot extrusion followed by cold rolling. The starting 2Mg–Fe mixture was obtained by high-energy ball milling. The cold-rolled samples, which presented a favorable (002) texture in Mg, absorbed 5.23wt.% H2, almost the full capacity of Mg2FeH6, without any incubation time. This level of hydrogen absorption capacity was higher than the ones observed for the milled powders or the extruded samples. The hydrogen desorption temperatures were very close for all types of samples. The good results observed in the hot-extruded plus cold-rolled sample were explained by the smaller grain sizes, along with a favorable texture and the catalytic effect of residual Fe.

Highlights: [•] Samples of commercial Mg were processed by ECAP and Cold-Rolling. [•] ECAPed cross-section samples were oriented in the (101) direction. [•] Rolled samples were oriented in the (002) direction favorable to the hydrogenation. [•] The best H-sorption results were obtained for rolled with less texture toward (101). [ABSTRACT FROM AUTHOR]
