“…The presence of a high background at low angles in all XRPD patterns is due to the protective dome of the sealed sample holder. The use of this protective dome was required to prevent air exposure and formation of MgO phase [31]. The XRPD patterns show that Mg 2 FeH 6 was synthesized by ball milling regardless of starting compositions and milling atmospheres.…”

Abstract:In this study we investigated the synthesis and the hydrogen storage properties of Mg 2 FeH 6 . The complex hydride was prepared by ball milling under argon and hydrogen atmosphere from 2Mg + Fe and 2MgH 2 + Fe compositions. The samples were characterized by X-ray powder diffraction and scanning electron microcopy. Kinetics of hydrogen absorption and desorption were measured in a Sievert's apparatus. We found that the milling atmosphere plays a more important role on Mg 2 FeH 6 synthesis than the starting compositions. Ball milling under hydrogen pressure resulted in smaller particles sizes and doubled the yield of Mg 2 FeH 6 formation. Despite the microstructural differences after ball milling, all samples had similar hydrogen absorption and desorption kinetics. Loss of capacity was observed after only five cycles of hydrogen absorption/desorption.

“…In the case of Ti-based alloys, Zhang et al [5,6] studied the effect of cold rolling on the hydrogen sorption properties of Ti-22Al-27Nb alloy and found better hydrogenation kinetics for cold rolled samples but only for the first hydrogenation cycle. Magnesium alloys have been studied by a few groups using different SPD techniques or combination of them [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23]. These studies will be discussed in more details in the next sections but the general conclusion is that SPD techniques could improve the hydrogen sorption properties of magnesium alloys.…”

Abstract:In this paper we review the latest developments in the use of severe plastic deformation (SPD) techniques for enhancement of hydrogen sorption properties of magnesium and magnesium alloys. Main focus will be on two techniques: Equal Channel Angular Pressing (ECAP) and Cold Rolling (CR). After a brief description of these two techniques we will discuss their effects on the texture and hydrogen sorption properties of magnesium alloys. In particular, the effect of the processing temperature in ECAP on texture will be demonstrated. We also show that ECAP and CR have produced different textures. Despite the scarcity of experimental results, the investigations up to now indicate that SPD techniques produce metal hydrides with enhanced hydrogen storage properties.

“…Another disadvantage is the high air reactivity of Mg-based materials processed by HEBM. These materials should be handled under an inert atmosphere to avoid spontaneous ignition and deterioration of hydrogen storage properties [6].…”
