Summary: Alloying elements such as Ru, Nb and Ta were added to improve the corrosion resistance of ASTM Grade 13 titanium alloy. Ru mainly formed beta-Ti precipitate, while Nb and Ta were detected in both beta-Ti and Ti2Ni precipitates. Ta was found to act as both a substitution element and a solid solution element, and had the greatest impact on the stability of the TiO2 film against high reducing conditions. Other alloying elements like Nb and Ru mainly influenced cathodic modification. EIS results confirmed the excellent effect of Ta in improving the stability of the TiO2 film.

Summary: This study improves the microstructure and mechanical properties of titanium alloys using electric pulse treatment and hydrogen as temporary alloying element instead of traditional thermo-mechanical treatment and heat treatment. The microstructure of the alloy after pulsed thermal hydrogen treatment is homogeneous and finer, leading to improved ultimate tensile strength and total elongation. The acceleration of atomic diffusion and phase transformation by hydrogen and electric pulse treatment leads to the decomposition of the lamellar 8 phase, refining the microstructure and enhancing mechanical properties.

Summary: The phase composition, microstructure, and hydrogen absorption/desorption properties of Mg1.8Y0.2Ni1-yCoy alloys (y = 0, 0.05, 0.1, 0.15, 0.2) were studied using XRD, SEM/EDS, PCT, and DSC techniques. The addition of Co did not affect the phase composition, but refined the microstructure of the alloys. Co addition improved the de-/hydrogenation kinetics and reduced the onset decomposition temperature of the alloys.

Summary: The hydrogen storage behavior of 3d TM doped small Mg clusters was studied using dispersion corrected density functional theory (ωB97X-D DFT) method. The hydrogenation reactions of TMMgn clusters with TM: Mg alloying ratio of 1: 1, 1: 2 and 1:3 were tested, and the maximum hydrogen storage capacity was observed for the 1:1 ratio. The gravimetric density of molecular hydrogen for VMg, FeMg, and NiMg dimers was found to be 11.8 wt%, 9.1 wt%, and 6.8 wt%, respectively. The study also showed that the geometry of the clusters played a crucial role in hydrogen adsorption, as isomers with exposed TM atoms could adsorb the maximum number of H2 molecules. Furthermore, the selectivity based on size, geometry, and alloying ratio of the clusters was established for their hydrogen storage performance.

Summary: The electrochemical hydrogen storage properties of 25 h milled Mg0.80Ti0.175Mn0.025ZrxNi1-x (x = 0, 0.025, 0.05, 0.1) quinary alloys were investigated. The substitution of Zr for Mg or Ni leads to an increase in structural disorder and amorphization. The Mg0.80Ti0.175Mn0.025Zr0.10Ni0.90 alloy exhibited the best discharge capacity of 604 mA h g-1 at the initial charge/discharge cycle. Using multi-component compositions is beneficial for enhancing the structural and cyclic stability of MgNi-based alloys, and substituting additive elements for Mg or Ni may offer impressive performance for efficient hydrogen storage applications.

This paper introduces a newly discovered process called self-shearing reactive milling (SSRM), which simplifies the activation process and achieves full hydrogenation of FeTi alloys through intense movement of particles. This process exposes a fresh active alloy surface, allowing hydrogen absorption without thermal treatment or evacuation.

Summary: The synthesis of a complex hydride Mg-2(Fe, Cr, Ni)H-x via reactive ball milling process of AISI 316 L stainless steel and magnesium hydride was presented. The results show that the reaction between magnesium hydride and 316 L steel proceeded faster than with pure iron, resulting in a material with a cubic K2PtCl6 structure. Additionally, the obtained samples had a hydrogen content of around 4 wt% and the synthesized sample was able to absorb 1% of hydrogen at -50 degrees c through the formation of magnesium hydride.

Summary: For the first time, the thermodynamic properties of liquid Mg-Pb-Pd alloys were studied through calorimetric measurements using a MHTC 96 drop calorimeter. Five series of liquid alloys were evaluated at a temperature of 1012 K, and the ternary excess term of the Mg-Pb-Pd liquid phase was determined based on the obtained data and the Redlich-Kister equation. Thermodynamic optimization was performed using home-made software, resulting in ternary optimized parameters. These measurements represent the initial step towards understanding the phase equilibria in the Mg-Pb-Pd system.

Summary: Samples of 316L SS were manufactured using Laser Engineered Net Shaping (LENS(R)) with different technological parameters. The samples were analyzed for microstructure, mechanical properties, phase content, and corrosion resistance. The manufacturing parameters had minimal impact on microstructure and mechanical properties, but affected corrosion resistance. All additively manufactured samples showed better corrosion resistance than the reference material and possessed austenitic microstructure without detectable ferrite.

Summary: In this paper, the interactions between mechanically alloyed Mg6Pd1-xAgx alloys and hydrogen were studied. The structures of the alloys were analyzed using X-ray diffraction (XRD), which confirmed the presence of a single Mg6Pd-type phase for samples with up to x=0.5 silver concentration. The kinetics of hydrogenation process and the properties of synthesized hydride were investigated using a Sievert-type sorption analyzer and differential scanning calorimetry (DSC) with thermogravimetric analysis (TGA). The results showed that partial substitution of palladium with silver improved the hydrogen sorption kinetics compared to pure Mg6Pd intermetallic phase, but resulted in lower hydrogen content. The influence of silver on the decomposition kinetics was also observed.
