Summary: The effects of grain refinement and precipitate evolution on the mechanical performance of Mg-12Gd-2Er-0.4Zr alloy fabricated by double extrusion are analyzed. The results show that double extrusion leads to the fragmentation of bulky precipitates and the formation of fine precipitates, resulting in a refined grain structure and increased content of rare-earth elements. The presence of fine precipitates and refined grains contributes to a high yield strength and elongation in the alloy.

Summary: The synergistic effects of copper addition and hot extrusion process were studied on the modification of microstructure and enhancement of mechanical properties of a common in situ hypereutectic Mg-Si metal-matrix composite. The results showed that copper addition at a microalloying level of 0.5 wt% effectively modified the microstructure and improved the mechanical properties of the as-cast material. However, higher copper additions led to poor tensile properties due to the deleterious effects of eutectics. The hot extrusion process resulted in fragmentation and dispersion of intermetallics, as well as intense grain refinement by dynamic recrystallization, leading to enhanced mechanical properties of the composites.

Summary: This review article provides an overview of the hot deformation behavior and constitutive description of flow stress in high entropy alloys (HEAs). The potential of hot working for grain refinement, reduction of casting defects, and enhancement of mechanical properties of HEAs is explained. The effects of processing parameters, alloying elements, dynamic precipitation, and the presence of phases on the hot deformation behavior and restoration processes are discussed. The application of processing maps for characterizing flow instability, cracking, flow softening, and dynamic recrystallization during hot forming of HEAs is presented. Various constitutive models and methods for flow stress modeling and flow curve prediction are assessed. Suggestions for future research works are proposed.

Summary: In this study, WE43-based nanocomposites were fabricated by adding nano- and micro-sized particles and using friction stir processing. The effect of particle size and geometry of particle insertions on the microstructure and corrosion properties of Mg-based composites was investigated. The results showed that the grain size of the composite matrix was reduced after friction stir processing, and there was a significant fragmentation and redistribution of secondary phase particles. The corrosion behavior of the composite was evaluated using various tests, and it was found that the corrosion mechanism involved both pitting and uniform corrosion. Furthermore, friction stir processing and addition of particles reduced the rate of electrochemical corrosive reactions. The composite fabricated with hole insertion and nano-sized particles exhibited a more uniform distribution of additives and higher corrosion resistance compared to the groove insertion method. Additionally, the composite sample with Cu/ZnO particles showed the highest anti-corrosion properties.

Summary: The grain refinement mechanism of Mg-9 Al alloy with SiC nanoparticles addition was investigated using a combination of experimental characterizations and sharp-interface model simulations. The experiments revealed the formation of a multilayer coating near the grain boundaries by the nanoparticles, leading to a reduction in mean grain size as the volume fraction of nanoparticles increased. The simulations supported the primary interaction between the nanoparticles and the moving solid-liquid interface being the pushing of nanoparticles towards the vicinity of grain boundaries. The dominant mechanism identified in this study was the growth restriction through blocking solute diffusion.

Summary: In this study, the reorientation of texture and improvement of mechanical properties in ZK61-T6 and ZK61-PC magnesium alloys were achieved through cross pre-compression. The results showed that the compressive yield strength, ultimate compressive strength, and elongation to fracture were significantly increased. The microstructure evolution revealed the propensity and width of adiabatic shear band and the role of twinning, de-twinning, and dislocation in absorbing high-stress energy. The twinning-induced rotational dynamic recrystallization mechanism contributed to the development of fine grains. Based on the findings, pre-compression is recommended as a practical approach to enhance the efficiency of ZK61 magnesium alloy.

Summary: The study focused on enhancing the mechanical properties of AZ91 magnesium alloy through the addition of a newly developed Al-5Ti-2B master alloy and subsequent hot extrusion process for structural refinement. The results showed that the grain refinement achieved through the addition of the master alloy and hot extrusion process led to an improvement in mechanical properties, with a superior strength-ductility trade-off compared to the as-cast counterparts. This was attributed to the disappearance of the grain boundary beta-Mg17Al12 phase and the formation of a recrystallized and homogeneous microstructure in the extruded alloys.

Summary: The deformation behavior of a twin-roll cast Mg-6.8Y-2.5Zn-0.4Zr alloy during plane strain compression was characterized by high-temperature testing in this work. The precipitation of LPSO phases during cooling to forming temperature after heat treatment contributes to the retardation of the DRX process, while at higher deformation temperatures and strain rates DRX is pronounced with TRDX and continuous dynamic recrystallization identified as the dominant softening mechanisms. Processing maps were established by superimposing the instability map over the power dissipation map, revealing two instability zones for the alloy where deformation is not favorable.
