Summary: This study provides an analysis of the ECAB process on thin hot-rolled AZ31 magnesium alloy sheets, investigating the effects of deformation temperature and strain path on texture evolution and mechanical properties. The study reveals that during ECAB, multiple twinning types are activated simultaneously, leading to a tilted component of basal texture. It also shows that an increase in uniform elongation over 60% with a marginal reduction of tensile strength less than 5% can be achieved through ECAB, attributed to larger fraction of grains favored with extension twinning and better local strain accommodation.

Summary: In this study, transverse gradient extrusion (TGE) processes with different die inclined angles were used to produce Mg-3Al-1Zn sheets, aiming to tailor their texture and mechanical properties. The microstructure, deformation texture, and final mechanical properties of the obtained sheets were analyzed and discussed. The rheological behavior of Mg alloys during extrusion was also analyzed using the finite element method. The results showed that the TGE die inclined angle influenced the flow velocity and effective strain difference during extrusion, leading to changes in the microstructure and texture of the extruded sheets. Higher TGE die inclined angles resulted in finer grain size and more uniform microstructure. The TGE-45 sheet exhibited a large elongation and low yield stress.

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 magnetic/polyetherimide-acrylonitrile composite nanofiber membrane with effective adsorption of nickel ions in an aqueous solution was successfully prepared using a simple electrospinning method. The high adsorption capacity of the membrane on nickel ions was attributed to the combination of magnetic NPs, polyetherimide-acrylonitrile matrix, and the nanostructure of the membrane, as confirmed by various characterization techniques and models. The membrane has the potential to be an environmentally friendly and nontoxic adsorbent for the removal of nickel ions in aqueous media due to its ease of preparation and use, as well as its stability in aqueous media.

Summary: The influence of magnesium (Mg) on the mechanical properties and corrosion behavior of Al-4Cu-xMg-0.6Ag alloys was investigated. The microstructure formed after the aging process was identified using Optical Microscope, SEM, XRD analysis, and Thermo-Calc simulation. Hardness and tensile strength testing, as well as corrosion testing, were conducted. It was found that Mg significantly impacts the hardness of the alloys, with a high Mg content increasing the hardness but reducing the tensile strength and ductility. The corrosion activity was reduced in the high-Mg-content alloy due to its larger particle size and reduced galvanic cell effect.
