Hydrogenation effect on microstructure and mechanical properties of Mg-Gd-Y-Zn-Zr alloys

Ultrafine-Grained Magnesium Alloys for Hydrogen Storage Obtained by Severe Plastic Deformation

“…Other authors investigated the effect of ECAP on the hydrogen sorption properties of such magnesium alloys as AZ31 (Leiva et al, 2009;Chiu et al, 2018;Skryabina et al, 2019), AZ61 (Huang et al, 2018), Mg-Mm-Ni (Mm = mischmetal) (Løken et al, 2007), and Mg-Gd-Y-Zn-Zr (Lapovok et al, 2018)-with various degrees of success. Useful summaries of the results obtained by employing ECAP as a tool for tuning the hydrogen sorption properties of Mg alloys was recently provided by Wang et al (2017) and Huot et al (2012).…”

Significant decrease of hydride decomposition enthalpy in ordered Mg-In alloys induced by growing hydrogen concentration

“…Using Mg-based alloys with a tendency to longperiod stacking order (LPSO) [27] may be a new way how to decrease the thermodynamic stability of MgH 2 and, at the same time, to preserve other favorable features of Mg-based HS alloys. It was reported that LPSO in complex HS alloys led to nucleation of phases formed during hydrogenation that acted as a very fine distributed catalyst for hydrogen storage [27][28][29][30][31][32]. Therefore, it is highly eligible to orient future research in this direction.…”

“…Based on recently published results, utilization of LPSO phases seem to be also a novel way, how to improve HS performance. New Mg-based hydrogen storage materials (HSMs) with LPSO were investigated, e.g., in [23,[27][28][29][30][31][32][34][35][36]. Their interaction with hydrogen was studied, e.g., in [22,29,30,32,37,38].…”

Possible facilitation of HS in LPSO structures was reported, e. g., in [30,31,37], where the authors showed that complex several-stage sorption reactions running in HSM with LPSO could decrease overall energy budget of the sorption process as a whole.…”

The beneficial effect of LPSO is not straightforward.…”
