Summary: This study systematically investigated the mechanical behavior of Mg AZ31 rods under tension along the extrusion direction and the relationship with bimodal texture components. The results showed that the yield strength does not decrease linearly with an increase in the percentage of soft orientations. Bimodal texture components stimulate the activation of twin variants with a low Schmid factor, indicating that the interaction among twin variants plays a major role in twinning behavior.

Summary: Dual-phase Mg-Li alloys with different rolling paths were studied to investigate the effect of rolling path on microstructure, texture and mechanical anisotropy. The lamellar alpha+beta structures remained after ED-rolling and subsequent annealing, while disappeared after TD-rolling. The texture of beta phase was hardly affected by the rolling path. Annealing only reduced the maximum intensity of texture without changing the type of texture. VPSC simulations revealed that the activated deformation modes and alpha/beta phase boundaries played important roles in texture evolution. There was an obvious mechanical anisotropy after ED-rolling, which disappeared after TD-rolling.

Summary: The study investigated the correlation between microstructure/texture evolutions and high temperature flow behavior in Mg alloy containing long period stacking order (LPSO) phases. The annealing treatment effectively strengthened the alloy and decreased ductility, with blocky LPSO assisting dynamic recrystallization and lamellar LPSO increasing alloy strength. The findings suggest that microstructure and texture evolution play a significant role in the high-temperature behavior of the Mg alloy.

Summary: A dual-textured Mg-6.5 Zn alloy with limited yield asymmetry is studied. The deformation mechanisms responsible for the behavior are analyzed and it is found that compressive deformation is accommodated by basal slip and extension twinning, while tensile deformation promotes basal and nonbasal slip. The contribution of rotated grains leads to similar values of the yield strength in tension and compression.

Summary: After cold-rolling an Mg-6Zn-0.3Ca alloy sheet with a strong basal texture, anomalous double twinning occurred with the (0001) pole aligned to the transverse direction. These twins served as nucleation sites for statically recrystallized grains during annealing, resulting in weak texture features in the annealed sheet with transverse-direction split (0001) poles.

Summary: The excellent work hardening in TRIP-enabled metastable high entropy alloys is attributed to the phase transformation from austenite to martensite, as well as non-basal slip activity and deformation twinning. A five-parameter empirical model has been developed to replicate the work hardening rate in TRIP HEAs, with easy parameter identification compared to physically based models. The model parameters are correlated with stacking fault energy to predict the tensile stress-strain response of TRIP HEAs.

Summary: This paper reports the application of cold-sample rolling (CSR) processing in a Mg-6Al-1Zn alloy sheet, which resulted in a high fraction of double twins and a substantial texture-weakening effect. Compared to high-temperature rolling (HTR) processing, CSR processing induced a relatively higher texture-weakening effect. The results indicate that twinning-mediated static recrystallization is essential for texture weakening in Al-concentrated Mg-alloy sheets.

Summary: We report the formation of an unusual texture on the sheet-surface of a rolled Mg-3Al-0.4Mn alloy, where a typical basal texture is formed at the center of the sheet and an unusual texture with vertical tiling is observed at the sheet-surface. The surface promotes prismatic slips and dynamic recrystallization, leading to a high fraction of fine basal-textured grains and a small fraction of off-basal-textured grains. In contrast, the center preserves a relatively high fraction of deformed grains, promoting the growth of basal-textured grains and the formation of the typical basal texture.

Summary: This study investigates the origin of the unique parallel alignment of (0001) poles to the transverse direction in rolled alloy sheets. It is found that intermediate reheating during rolling facilitates static recrystallization and leads to the formation of the parallel alignment of (0001) poles to the transverse direction. In contrast, continuous rolling without intermediate reheating suppresses the formation of the unique alignment. The presence of severely deformed regions near double twins hinders the nucleation and growth of statically recrystallized grains, resulting in in-plane anisotropy in ductility.

Summary: This study investigates the effects of age hardening on different types of twinning in magnesium alloys, specifically in alloy Mg-6.5Zn with bimodal textures. It was found that tensile twinning is stimulated by precipitates while compression twinning is suppressed by them. This difference is attributed to lower twin surface energy and a larger twinning dislocation Burgers vector in compression twins.

Summary: In the Mg-7Sn-3Zn-0.04Na alloy, the critical shear stress for achieving 5% twinning is increased by the presence of 7% of Sn and by the presence of particles formed after 10 hours of aging. The evolution of twin volume fraction with plastic strain is similar in both non-aged and aged conditions, indicating precipitation hardening is particularly sensitive to relaxation effects.

Summary: High-chromium cast irons are commonly used for wear-resistant applications, and there is ongoing debate on the secondary carbide types during heat treatment. This study examines the microstructural evolution of a hypoeutectic high-chromium cast iron and finds that M23C6 secondary carbides precipitate during heating, while higher temperatures result in the formation of both M23C6 and M7C3 secondary carbides. The carbon content of the matrix plays a significant role in determining the martensite start temperature and bulk hardness.

Summary: This work investigates the formation of adjoining twin pairs (ATPs) at grain boundaries (GBs) in hexagonal close-packed (hcp) metals, focusing on the co-nucleation (CN) of pairs of deformation twins. A continuum defect mechanics model is proposed to study the energetic feasibility of CN of ATPs resulting from GB dislocation dissociation. The model reveals that CN is preferred over the nucleation of a single twin variant for low misorientation angle GBs. Further analysis considering GB character and twin system alignment suggests that CN events could be responsible for ATP formation even at low m' values.

Summary: This study investigates the behavior of electric-field induced antiferroelectric to ferroelectric (AFE-FE) phase transition and reveals the evolution of atomic displacement ordering as the cause for the transition behavior changing from sharp to diffuse. The novel semi-ordered configuration results from the competing interaction between long-range displacement modulation and compositional inhomogeneity, which leads to a diffuse AFE-FE transition while maintaining the switching field.

Summary: In this work, a physics-constrained neural network is used to predict grain-level responses in FCC material by incorporating crystal plasticity theory. The key feature, shear strain rate of slip system, is identified based on crystal plasticity and incorporated into the loss function as physical constitutive equations. The introduction of physics constraints accelerates the convergence of the neural network model and improves prediction accuracy, especially for small-scale datasets. Transfer learning is performed to capture complex in-plane deformation of crystals with any initial orientations, including cyclic loading and arbitrary non-monotonic loading.

Summary: This study attempts to address the gap in cooling rates between thin film deposition and bulk metallic glass (BMG) casting by correlating the glass-forming range (GFR) determined from combinatorial materials chips (CMCs) with the glass-forming ability (GFA) of BMG. The results show that the full-width at half maximum (FWHM) of the first sharp diffraction peak (FSDP) is a good indicator of BMG GFA, and strong positive correlations between FWHM and the critical casting diameter (Dmax) are observed in various BMG systems. Furthermore, the Pearson correlation coefficients suggest possible similarities in the GFA natures of certain BMG pairs.
