Summary: The influences of Sc/Sm microalloying on microstructure, mechanical property, bio-corrosion behavior and biocompatibility of the as-cast Mg-2Zn-0.3Ca alloy have been investigated. Sc microalloying refines the grain and improves the yield strength, while Sm microalloying promotes the formation of dispersed particles. Mg-2Zn-0.3Ca-0.4Sm alloy exhibits the best corrosion resistance and protective layer, and is non-cytotoxic and promotes cell proliferation.

Summary: A composite material based on the WE43 magnesium alloy containing nano-sized hardystonite ceramic particles was processed by friction stir processing (FSP), resulting in improved compressive strength, strain-at-failure, and corrosion resistance. The corrosion mechanism of the nanocomposite involves a combination of uniform corrosion and localized pitting corrosion, similar to the base metal, but with significantly reduced corrosion rate.Enhanced properties were attributed to grain refinement, fragmentation, and redistribution of second-phase particles in the magnesium matrix during FSP.

Summary: In this work, the microstructure, corrosion resistance, and discharge properties of the as-extruded Mg-7Li-1Y alloy were studied. The alloy exhibited a bimodal microstructure mainly composed of alpha-Mg and beta-Li phases. Despite poor corrosion resistance, it showed remarkable discharge performance with a discharge voltage of 1.35 V and a high anode utilization rate of 59% at a current density of 10 mA/cm2. The unique morphologies of discharge products and the presence of beta-Li phase contributed to the improved electrochemical activity and discharge performance.

Summary: The corrosion behaviors and mechanism of Mg-xZn-0.5Er (x = 0.5, 2.0, 3.0 and 4.0, in wt.%) alloys were investigated. The potential difference between the second phase and matrix was determined by the type and size of the second phases. The dominated nano-scale W-phase on the matrix induced sharp local pitting corrosion, while an increase in the volume fraction of the coarse W-phase or I-phase resulted in preferential corrosion around them, leading to obvious uniform corrosion and an accelerated corrosion rate.

Summary: This paper investigates the corrosion behavior of Mg-5.7Gd-1.9Ag alloy sheets in a salt solution. The results show that the rolled sheets exhibit better corrosion resistance compared to the as-cast sheets. Aging treatment decreases corrosion resistance, but it still remains higher than that of the as-cast sheets. The migration of corrosion is mainly influenced by the evolution of second phases rather than grain size and texture.

Summary: This study proposed a new strategy to indirectly estimate the hydrogen diffusivity of metallic materials under tensile stress by combining the electrochemical hydrogen permeation test (EHPT), the hydrogen diffusion descriptive equation based on Fick's law, and hydrogen pre-charged tensile test. The results showed that the hydrogen permeation curve obtained was highly approximate to the theoretical trend. The hydrogen embrittlement (HE) susceptibility of the specimens increased with increasing stress.

Summary: Deposition of Pd/Pt/Au three-layer films on p-GaN under high and ultra-high vacuum conditions was studied to investigate the electrical contact properties. Linear I-V curves were observed in samples deposited under ultra-high vacuum conditions, while nonlinear I-V characteristics were obtained in samples deposited under high vacuum conditions. The study also found that the samples deposited under high vacuum conditions had higher amounts of oxygen and Pd oxide. The oxide layer had an additional influence on the electrical characteristics of the Pd/Pt/Au/p-GaN contact.

Summary: The corrosion behavior and microstructural evolution of Sc microalloyed Al-3.2Cu-1.5Li alloys were investigated in detail. The microstructural results showed higher levels of dislocations density in the Sc microalloyed sample, which resulted in significantly refined grains and T1 precipitates. Microalloying with Sc changed the corrosion mode of the alloy and localized corrosion was found to occur preferentially at the subgrain within unrecrystallized grains with high grain stored energy.
