Summary: A novel coating on the Mg1Mn alloy was produced by anodic polarization combined with hydrothermal treatment (AP + H) in 0.1 M Na2CO3 solution. The coating consisting of MgCO3, Mg(OH)(2), and MgO provided satisfactory protection in 3.5 wt% NaCl, but showed increased corrosion rate after 72 hours. The failure of the coating was attributed to second phase particles or impurities in the matrix. The AP + H coating is considered suitable as a primer coating for Mg applications in kitchen ware, biomedical areas, or industry.

Summary: In this study, plasma electrolytic oxidation (PEO) coatings on magnesium alloy were produced and followed by hydrothermal treatments to synthesize layered double hydroxides (LDHs) based nanocontainers. The synthesis of LDHs was performed in different growth solutions. The results showed that it was difficult to form LDHs on silicate-based PEO coating, while hydrothermal treatments in Al3+ containing solution played an important role in corrosion resistance for phosphate and silicate-based PEO coatings.

Summary: Mg-10Gd-3Y-0.5Zr alloy castings show great potential for aerospace applications due to their excellent tensile and creep properties. The hot tearing behavior of these alloys, which is an important characteristic for engineering applications, is investigated in this study through the addition of minor amounts of Ag and Ce. The results show that the addition of Ag and Ce worsens the hot tearing resistance of the alloy, with Ag increasing the susceptible freezing range and coefficient of thermal expansion, and Ce increasing grain size and coefficient of thermal expansion.

Summary: The micro addition of Ca effectively increases the strength and ductility of Mg-Zn-Ce alloy by enhancing alloying segregation at grain boundary. The addition of Ca leads to enhanced Zn segregation and co-segregation of Zn, Ce, and Ca. This is attributed to the decreased segregation energy and promoted diffusion process of Zn by Ca, which accelerates the thermodynamic and kinetic process of segregation. The controllable segregation at grain boundary, induced by Ca, contributes to the development of advanced magnesium alloys by stabilizing grain boundary, refining grain size, inhibiting dislocation mobility, improving strength, and enhancing grain boundary cohesion and ductility.

Summary: In this study, a novel alloy designing concept is proposed to prepare a Mg alloy with excellent strength-ductility synergy by refining grain size and depressing intergranular deformation simultaneously. Through extrusion at 220 degrees C, an ultrafine microstructure is achieved in the basic alloy, Mg-1Sb-1Mn (SM11). The co-addition of Sn and Zn is then conducted to inhibit intergranular deformation and improve the mechanical properties of the alloy. The results show that the strength of the extruded Mg-1Sb-1Mn-1Sn-0.2Zn (SMTZ1110) alloy is significantly improved while maintaining a high ductility, suggesting a promising approach for the development of Mg alloys with a balanced strength-ductility combination.

Summary: A new strategy using N2O as a reaction gas for the simultaneous determination of nonmetallic impurity elements in high-purity magnesium alloys by ICP-MS/MS was proposed. Through O-atom and N-atom transfer reactions, spectral interferences were eliminated and higher sensitivity and lower LODs were achieved compared to other reaction modes. The accuracy of the method was evaluated and it showed consistent results with SF-ICP-MS. This study provides a systematic method for precise quantification of impurity elements and can be applied to other fields.

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: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
