Summary: In this study, Mg85Ni14Ce1 amorphous alloy films with different thicknesses were prepared, and the nanosize effect on hydrogen desorption and cycling properties was investigated. It was found that as the size decreases, the hydrogen storage kinetics of the alloy greatly increase, and the nanosized amorphous alloys can reversibly absorb and desorb hydrogen at a low temperature. Moreover, the alloy structure can be fully recovered after hydrogen absorption and desorption cycles. Therefore, nanosized amorphous alloys are promising candidates for reversible hydrogen storage applications.

Summary: Alloys based on Ti-Zr are considered ideal for hydrogen storage applications. This study investigates the substitution of Fe for Ni in the Ti45Zr38Ni17 compound. It is found that the substitution leads to the transformation of the amorphous phase into the icosahedral quasicrystalline phase, and this transformation is a continuous process. At higher temperatures, the quasicrystalline structure further transforms into other phases. The investigated alloy exhibits a good capacity for gaseous hydrogen at elevated temperatures.

Summary: The hydrogen storage properties of amorphous and crystalline Mg85Ni5Y10 alloys were compared, and the melt-spun alloy showed higher storage capacity and faster kinetics than the induction-melted alloy. The reversible storage capacity of the melt-spun alloy was 4.2 wt% H2, while the induction-melted sample had 3.8 wt% at 200 degrees C. Furthermore, the melt-spun alloy could release 4.1 wt% H2 within 30 min at temperatures above 275 degrees C, close to its theoretical hydrogen storage capacity of 4.2 wt%.

Summary: Bulk materials of the Mg-Ni-Nb2O5 alloy with ultrafine grain structure produced by high-pressure torsion (HPT) processing exhibit faster hydrogenation kinetics and higher storage capacities compared to initial mild-milled powder mixtures. However, the storage capacities are limited by the formation of MgO after several hydrogenation cycles. Despite this limitation, the material can be handled and stored without special precautions and maintains its fast activation in posterior hydrogenation treatments for several months.

Summary: This study investigated the effect of Ca concentration on the microstructure, mechanical properties, and thermal conductivity of Mg-2Ga-xCa (x = 0, 0.2, 0.4, and 0.8 wt.%) alloys at room temperature. Increase in Ca content led to a decrease in grain size and volume fraction of recrystallized grains, resulting in increased yield strength. However, it also caused an increase in the number and size of second phase particles, leading to reduced plasticity. Minor Ca additions (0.2% and 0.4%) had no significant effect on thermal conductivity, but 0.8% Ca addition significantly improved the thermal conductivity of both as-cast and as-extruded alloys. The as-extruded Mg-2Ga-0.8Ca alloy exhibited a tensile yield strength of 244 MPa and a thermal conductivity of 135.5 W·m-1·K-1. It is suggested that Mg alloys with high strength and high thermal conductivity can be designed by selecting appropriate alloying elements to form precipitates instead of dissolving in the Mg matrix.

Summary: The microstructure, structure, and overall performance of Nd-Fe-B regenerated magnets are studied after adding low melting point Ho69.3Ni30.7 alloy at the grain boundary. The addition of Ho69.3Ni30.7 alloy optimizes the distribution of the grain boundary phase and weakens the exchange coupling effect between adjacent main phases. It also increases the coercivity and curie temperature of the regenerated magnet. The research achieves the secondary utilization of waste Nd-Fe-B magnets and greatly improves the absorbing performance.
