Summary: The study determined a narrow temperature range of changes in the mechanism and kinetics of structural-phase transformations during mechanical alloying in high-nitrogen chromium-manganese steel, leading to abnormal behavior of the mechanical properties of the steel. The direction of nitrogen redistribution was found to change due to the acceleration of the decomposition of nitrogen-supersaturated solid solution of austenite with the formation of secondary nanocrystalline nitrides.

Summary: There is great interest in using severe plastic deformation (SPD) to improve the performance of magnesium for biological applications. However, contradictory reports exist regarding the properties and trends. This study reviews the structural features, mechanical properties, corrosion behavior, and biological response of magnesium and its alloys processed by SPD, with a focus on equal-channel angular pressing (ECAP) and high-pressure torsion (HPT). The results show that grain refinement through SPD can improve the mechanical properties and corrosion resistance of magnesium without compromising the biological response, indicating the great potential of SPD for enhancing the performance of magnesium for biological applications.

Summary: By fabricating V4Nb18O55 microspheres, the H-2 desorption and absorption properties of MgH2 can be improved and the uniform formation of Nb/V interfaces can be achieved, resulting in the reduction of dehydrogenation temperature of MgH2 and the enhancement of hydrogenation reaction rate.

Summary: This study proposes a new variable circular channel angular extrusion (VCCAE) process for manufacturing magnesium alloy plates with rib-web structure. The feasibility and accuracy of the process are validated through numerical simulations and experiments. The results show that stress and strain distribution in the longitudinal section is highly inhomogeneous, with significant stress concentration at the shear plane. The microstructure in the angular region is more uniform and finer, indicating that severe shear deformation induced by the angular channel promotes deformation uniformity and grain refinement.

Summary: We studied the synthesis reaction of Mg2NiH4 hydride films and found that a dense polycrystalline film of Mg2NiH4 hydride grows on a thin underlayer of intermetallic alloy MgNi2. The interface between MgNi2 and Mg2NiH4 is the most probable location of the growth reaction. We also observed cathode luminescence spectra of the Mg2NiH4 hydride film, which showed that Mg2NiH4 is an indirect gap semiconductor with a gap value of approximately 1.6 eV.

Summary: Severe plastic deformation has been shown to significantly improve the mechanical strength, ductility, and corrosion resistance of pure magnesium, particularly for biodegradable applications. Processing methods such as ECAP and HPT can reduce anisotropy, increase strength, and enhance strain rate sensitivity in the material. Furthermore, severe plastic deformation has been found to induce uniform corrosion and reduce the overall corrosion rate compared to as-cast material.

Summary: Ti2AlC and Ti3AlC2 are part of the MAX phases, a family of layered compounds. The study tests a composite approach to improve the brittleness of these compounds. Surface severe plastic deformation (SSPD) was conducted on a bulk MAX compound and a MAX/TiAl2 composite using surface mechanical attrition treatment (SMAT). The presence of intergranular TiAl2 effectively prevented failure in the composite, resulting in a surface hardening gradient extending down to a depth of 250 μm.

Summary: This study systematically investigated the mechanism by which Li additions induce a more homogeneous deformation in Mg. The results showed that the addition of Li dramatically reduced the critical resolved shear stress of pyramidal (c+a) slip, facilitating easy and uniform deformation propagation and improving deformation homogeneity.

Summary: Understanding the dynamic precipitation of LPSO phase and its effect on dynamic recrystallization in Mg-based alloys can provide insights for the manufacturing of high-performance alloys. This study found that the increase of Y and Zn atoms promotes the dynamic precipitation of 14H-LPSO phase in non-DRX and DRX grains respectively during hot extrusion.

Summary: The study used nanoindentation to investigate the local mechanical properties near 1010 tilt grain boundaries in magnesium bicrystals with different misorientation angles. It was found that critical shear-stress for the second pop-in differed substantially for grain boundaries with different structures, indicating important mechanical property variations in these boundaries.

Summary: The influence of drilling fluid on the physicomechanical properties of commercial rubbers was studied. Prolonged contact with the fluid resulted in increased stiffness and coefficient of mechanic loss of the rubber. It was also found that RTD-1 rubber exhibited higher stability than RTD-2 rubber when in contact with the drilling fluid. At 80 degrees C, the elastic-hysteresis properties of both types of rubber deteriorated by 30-50%.
