Summary: Ball milling Mg-based alloys with transition metal compounds enhances their hydrogen storage performances. In this experiment, La1.7Y0.3Mg16Ni + x wt.% TiF3 (x = 0-10) alloys were prepared using mechanical milling technology. XRD, SEM, HRTEM, and granulometry were used to analyze the composition and microstructure. The addition of TiF3 improves the crystallinity, reduces particle and crystallite sizes, and enhances hydriding and dehydriding kinetics. Adding 7 wt% TiF3 decreases the dehydrogenation activation energy and improves the hydrogen absorption rate at low temperatures.

Summary: In this study, a quaternary alloy La7Sm3Mg80Ni10 was prepared using casting and ball milling procedures, and the structural changes during hydrogen sorption and desorption were investigated. The results showed that ball milling reduced the grain and particle size and altered their surface properties. Compared to the as-cast alloy, the as-milled alloy absorbed 4 wt% H2 in shorter times at different temperatures. The as-milled and as-cast alloys exhibited similar dehydrogenation enthalpy change (ΔH) and apparent activation energies for dehydrogenation (Ede).

Summary: The addition of TiO2 in magnesium based materials improves the efficiency of mechanical milling and enhances the hydrogen storage performance, especially in the as-milled (x = 5) alloy. The alloy exhibits an amorphous and nanocrystalline structure, and the TiO2 content has a slight effect on the thermodynamic properties of the alloys. The optimal hydrogen storage property is shown in the as-milled (x = 5) alloy due to its minimum dehydrogenation apparent activation energy.

Summary: The Mg90Ce5Y5 alloy was prepared by vacuum induction melting, and Mo, MoO2, and MoO3 were added to it through mechanical ball milling. The microstructure, phase evolution, hydrogen storage thermodynamics, and kinetics were studied using XRD, SEM, TEM, PCT, and DSC methods. The results showed that the internal phases of the Mo catalyzed alloy transformed into MgH2, CeH2.73, YH3, and Mo phases upon hydrogen absorption, while the hydrogenated alloy consisted of MgH2, CeO2, YH3, MgO, and Mo phases for the MoO2 catalyzed alloy, and MgH2, MgO, CeO2, Y2O3, and Mo phases for the MoO3 catalyzed alloy. REDOX reactions occurred between MoO2, MoO3, and the inner phase of the alloy. Compared to the others, the Mo catalyzed alloy exhibited a higher hydrogen absorption saturation ratio, and the MoO2 catalyzed alloy required less time to release H2 compared to the Mo and MoO3 catalyzed alloys. The dehydrogenation activation energy (Edes) of the samples showed an increasing trend in the order of MoO2 catalyzed alloy (110.18 kJ/mol).

Summary: Laser cladding was conducted using Cr7C3/Ni3Al alloyed powder and Cr3C2/Ni3Al mixed powder to prepare a Cr7C3 reinforced Ni3Al composite cladding layer. The microstructure and tribological properties of the cladding materials were studied, revealing that the alloyed powder cladding layer exhibited a microstructure mainly composed of Ni3Al, NiAl, and in-situ formed Cr7C3, while the mixed powder cladding layer contained Cr3C2. The alloyed powder cladding layer showed lower friction coefficient and wear loss compared to the mixed powder cladding layer, and was more friendly to its counterpart. The improved wear resistance of the alloyed powder cladding materials can be attributed to the homogeneous distribution of fine in-situ formed Cr7C3, effectively separating the friction pair.

Summary: This paper proposes a grey box model for fuel consumption prediction of wing-diesel hybrid vessels based on feature construction. By using both parallel and series grey box modeling methods and six machine learning algorithms, twelve combinations of prediction models are established. A feature construction method based on the aerodynamic performance of the wing and the energy relationship of the hybrid system is introduced. The best combination is obtained by considering the root mean square error, and it shows improved accuracy compared to the white box model. The proposed grey box model can accurately predict the daily fuel consumption of wing-diesel hybrid vessels, contributing to operational optimization and the greenization and decarbonization of the shipping industry.
