A new Mg-5.5Gd-3Y-1Sm-0.5Zr (1Sm) alloy was developed. The deformation behavior and microstructure evolution of the Mg-Gd-Y-(Sm)-Zr alloys during hot compression were investigated systematically. effects Sm element addition on workability dynamic recrystallization (DRX) Mg-5.5Gd-3Y-0.5Zr (0Sm) revealed. will increase thermal activation energy reduce discontinuous (DDRX) at 350 °C 400 °C. Mg5(Gd)-type phases are precipitated dynamically in Mg matrix low-temperature process, occurs near phase...
Strain rate plays an important role in the hot deformation process of materials. In this work, compression experiments were conducted on Mg-Gd-Y-Sm-Zr alloy at strain rates 0.001-1 s-1 by Gleeble thermal simulation machine. The behavior and microstructure evolution studied detail, dynamic recrystallization (DRX) mechanism was discussed. results show that flow stress increases with increasing rate. Deformation bands (DBs) are formed inside some grains 0.1-1 s-1, which increase interfaces...
As shear stress plays a significant role in the deformation of tubular parts with complex shapes, investigation microstructue evolution tubes under state is beneficial to understanding mechanism and promoting prediction accuracy numerical simulation. In this paper, experiments were conducted on thin-walled 5052 aluminum alloy tubes. The texture lattice rotation behavior tube during studied using in-situ electron back scatter diffraction (EBSD) technology. It shown that initial Cube remains...
The Mg-7Gd-4Y-2Zn-0.5Zr alloy chips were successfully recycled through isothermal sintering and equal channel angular pressing (ECAP). mechanical properties microstructure evolution of samples during the recycling process studied in detail. eutectic phases as-cast transform into long period-stacking ordered (LPSO) after homogenization, which can improve plasticity material. After sintering, density sample is lower than that homogenized sample, oxide films are formed adjacent to bonding...
Deep eutectic solvents (DES) have gained attention serving as sustainable substitute to conventional inorganic acids in hydrometallurgical recycling, offering strong leaching capabilities and environmentally friendly solutions for the extraction of valuable metals from used lithium-ion batteries. However, high viscosity limited capacity traditional binary DES systems hindered their practical application direct black mass spent Li-ion In this work, a ternary system formed choline chloride...
The popular constitutive models used in the field of hot forming magnesium alloys can be divided into phenomenological models, machine learning and internal state variables (ISV) based on physical mechanisms. Currently, there is a lack comparison evaluation regarding suitability different types models. In this study, Mg-Gd-Y-Zr alloy taken as research object. deformation behavior was studied systematically. Subsequently, Arrhenius model with strain compensation, artificial neural network...
Transportation and transformation of photogenerated carriers during the photocatalytic process graphitic carbon nitride (g-C<sub>3</sub>N<sub>4</sub>) are restricted by low surface area insufficient charge separation efficiency.
Ti/Al laminated composite fabricated by explosive welding has received widespread attention due to their potential in achieving excellent performance. However, investigations on the crack evolution and fracture behavior were still limited. In this paper, morphology elemental distribution of bonding interface investigated. And initiation propagation was investigated in-situ tensile test. It is shown that local melted zone (LMZ) formed along wavy interface, which mainly consisted TiAl2 + TiAl3...
Anisotropy is the difference in microstructure or mechanical properties of materials different directions. Anisotropic behavior occurs rolled sheets, and this anisotropy very obvious laminated composites. In work, influence on Ti/Al composites fabricated by rolling was investigated. The results show that were obviously anisotropic. grains Al layer elongated along direction compressed perpendicular to direction. Ti had no preferential orientation comprised mainly twins. With as 0°, varied...
Abstract AZ63 magnesium alloy sheets were fabricated by accumulative roll bonding (ARB) process at 350 °C up to 5 cycles.

The experimental data of the dielectric function gold films are vital in metal optics since optical and optoelectronic properties depend sensitively on function. Even though significant discrepancies exist among measurements past 60 years, contribution grain boundary is less studied. In this work, we measured three different using two ellipsometers covering spectral range from 200 nm to 25 μm. Based Drude model Mayadas-Shatzkes electron-grain scattering, find that electronic reflection...
Light polarization rotations, created by applied optical field, are examined experimentally and theoretically in a photosensitive chiral nematic fluid. The rotation of the transmitted beam is initiated illuminating sample with uniform UV light. operation tunable reversible, depending on intensity. It was revealed that rotations can be ascribed to optical-field-induced chirality effect, where helical structure nematics changes accordance evolution as well its effect light upon illumination...
