Summary: This study investigated the effects of twinning time node on the creep resistance of an extruded Mg-2wt%Y sheet. Pre-compression with a low strain before creep resulted in a large amount of {10 (1) over bar2} twins, impacting the creep resistance of the samples. The dominant creep mechanisms differed between samples with and without pre-compression, with the presence of twins affecting the creep rate.

Summary: The results of the study demonstrated a clear tension-compression asymmetry in the creep behavior of the alloy under tensile and compressive creep loading along the rolling direction and the normal direction. Twinning played a role in deteriorating the creep resistance of certain samples and causing asymmetrical behavior in the results. The T-RD sample showed the best creep resistance, while the C-ND sample followed, with the C-RD and T-ND samples showing similarly poor creep resistance.

Summary: In this study, a novel texture control strategy called shear strain-induced twin orientation regulation (SITOR) was used to fabricate the Mg-3Al-1Zn (AZ31) alloy with improved ductility. The SITOR-1P sample processed at 250 degrees C exhibited a homogeneous microstructure and an ideal shear texture, resulting in significantly enhanced fracture elongation. Increasing shear strain in the SITOR-4P sample further improved its mechanical performance. Conventional shear strain-induced orientation regulation (SIOR) method showed limited texture deflection and performance enhancement. The SITOR scheme offers a fresh perspective for addressing the poor plasticity of Mg.

Summary: Age-hardening has been considered as an efficient way to enhance the creep resistance, but it unexpectedly deteriorated the creep resistance of a hot-rolled Mg-8wt%Gd alloy in this study. The precipitates formed during peak-aging treatment promoted the cracking of grain boundaries, resulting in the worsening of creep resistance. Meanwhile, the precipitation strengthening gradually reduced, leading to the acceleration of creep rate.

Summary: This paper investigates the deformation behavior of a dilute Mg alloy during hot compression and finds that the activation of twinning and dynamic recrystallization is influenced by the strain rates. The study also reveals that the crystal orientation is altered by the activation of twinning and DRX processes, playing a significant role in the plastic deformation behavior of the alloy.

Summary: This study combines experimental micromechanical methods and analytical electron microscopy to analyze the influence of nanoprecipitation on soft and hard basal slip and twinning in a weakly textured, polycrystalline Mg-Gd-Y-Zr alloy. The results show that aging leads to extreme localization in grains favorably oriented for soft basal slip, while prismatic slip dominates deformation and twinning is favored in grains with the c-axis perpendicular to the compression axis. In grains deforming mainly by hard basal slip, precipitation leads to the strengthening of basal systems without obvious localization.

Summary: Due to the strain rate sensibility of magnesium alloys, the ratcheting behavior under cyclic loading was investigated and discussed at different frequencies. The results showed that the ratcheting strain and fatigue life exhibited two trends with frequency. In the frequency range of 0.02 Hz to 0.4 Hz, the ratcheting strain decreased and the fatigue life increased. In contrast, in the frequency range of 0.4 Hz to 2.0 Hz, the ratcheting strain increased and the fatigue life decreased. The frequency effect depended on the weight of the slip and twinning deformation mechanisms, which were related to strain rate, showing dual frequency domain characteristics.

Summary: The solute atom mediated Hall-Petch relations were investigated for Mg-Y, Mg-Al, Mg-Gd, and Mg-Zn alloys at a nominal solute content of 0.35 at.%. It was found that Mg-Y and Mg-Gd exhibited significantly lower Hall-Petch slope (k) values (220 MPa·μm(1/2) and 285 MPa·μm(1/2), respectively) compared to Mg-Al and Mg-Zn (324 MPa·μm(1/2) and 322 MPa·μm(1/2), respectively) under compression along the extrusion direction. The addition of Zn or Al led to a strong basal texture and predominantly basal slip deformation, while the addition of Gd or Y resulted in a weakened texture and activation of both {10 (1) over bar2} twinning and basal slip. This difference in deformation mechanisms contributed to the lower k values in Mg-Y and Mg-Gd alloys.

Summary: Temperature has a significant influence on the critical resolved shear stress (CRSS) of slips and twinning in Mg single crystals. Non-basal slip occurs in the temperature range of 613 to 733 K when the single crystal samples are stretched along the <01<($)over bar> 10 > direction, while basal slip and prismatic slip are mainly activated from room temperature to 733 K when the tensile directions are inclined at an angle of 45 degrees with the basal and the prismatic plane, respectively. CRSSs of different deformation modes show different temperature dependence.

Summary: The initial texture effect of strain rate sensitivity in magnesium alloys was studied using quasi in situ electron backscatter diffraction. The strain accumulations showed strain rate dependency under uniaxial loading. For AZ31 magnesium sheets with strong basal texture, twinning first occurs at the onset of deformation, resulting in macroscopic strain rate insensitivity. With further loading, strain rate sensitivity increases significantly due to slip initiation. For WE43 alloy sheets with weak basal texture, overall deformation is sensitive to strain rate under both tensile and compression. Twinning growth rate and twinned volume fraction are used to identify twin-dominated or slip-dominated process during plastic deformation of magnesium alloy.

Summary: Text classification is a fundamental problem in natural language processing. Graph-based models, such as GNN-based and GCN-based models, have recently been applied to this task and achieved excellent performance by modeling context from a global perspective. However, existing graph-based models often construct a corpus-level graph structure, leading to high memory consumption and overlooking local contextual information. To address these issues, this paper proposes a novel GNN-based model called TSW-GNN, which constructs a unique text-level graph for each text using two sliding windows. Extensive experiments on benchmark datasets demonstrate the improvement of TSW-GNN in classification accuracy compared to state-of-the-art models.

Summary: This paper presents a novel strategy for concrete curing using solar thermal energy storage based on phase change material (PCM), aiming to prevent frost damage to concrete at an early stage and promote rapid concrete strength growth in cold climates. The proposed method utilizes the latent heat of the thermal energy storage layer (TESL) containing PCM to continuously cure the concrete at a positive temperature, with a transparent insulation layer (TIL) to absorb thermal energy through solar radiation. The study also proposes a numerical method for designing the TESL under different climatic conditions, with an optimal thickness ranging from 0.87 cm to 4.86 cm. Experimental results demonstrate that the concrete specimens cured using this strategy achieve excellent temperature history and reach the design strength in just 60 hours. Economic evaluation results show that the proposed curing method is cost-effective and provides significant energy saving and emission reduction throughout the service cycle. This work provides an efficient and clean solution for rapid concrete construction in cold climates.

Summary: Drainage conditions and consolidation states can affect the deformation behavior of clayey soil under cyclic loading. The lateral deformation in soils under partially drained conditions is similar to those under undrained conditions with the increase of over consolidation ratio. Under undrained conditions, a large axial strain could accumulate with a small amount accumulation in excess pore water pressure, while under partially drained conditions, the resilient modulus of the soil decreases as the volumetric strain increases.

Summary: Recent evidence suggests that long-term exposure to PM2.5 is associated with depressive symptoms. However, little is known about the individual effects of PM2.5 components, especially in low-income and middle-income countries. Our study found that long-term exposure to major components of PM2.5 is significantly associated with worsening depressive symptoms in Chinese adults. Different components may have different levels of toxicity. Reducing PM2.5 emissions, particularly from major sources of organic matter and ammonium, may help reduce the burden of depressive symptoms in Chinese adults.
