Summary: The study investigated the texture evolution of a Mg-Zn-Ca plate during cold rolling and subsequent annealing. It was found that basal slip was the main deformation mode and prismatic slip preserved the TD-split texture. Pyramidal slip caused the widening of the basal texture. Grain nucleation occurred at grain boundaries, deformation twins, and near precipitates, with minimal texture change.

Summary: The interplay of Nb addition and annealing temperature in low carbon cold-rolled steel was investigated. The addition of Nb had a strengthening effect due to ferrite grain refinement and NbC precipitation, but the change in soft and hard phase fractions complicated its overall influence. Annealing at 770 degrees C with Nb addition resulted in a significant increase in strength, while annealing at 850 degrees C caused the decomposition of austenite and an increase in the soft phase fraction, leading to a decrease in yield and tensile strength.

Summary: This study investigated the recrystallization mechanism and texture evolution of Zr702 under different rolling modes. The results showed that cryogenic rolling activated {1012} and {1121} tensile twins, leading to a change in texture. Cross rolling activated prismatic slip more than tensile twinning, resulting in lower area fractions of tensile twins and slower texture change. However, the final textures of the two types of rolled samples at 30% thickness reduction were similar.

Summary: This study presents a new method to obtain recrystallized textures with rare-earth (RE) texture components through post-annealing of accumulative back extruded microstructures. It was observed that annealing at 400 degrees C for 30 min resulted in a homogeneous microstructure with RE texture components formed through precipitation of RE-rich particles and nucleation of new grains. Increasing the annealing time to 240 min (or raising the temperature to 450 degrees C) led to disappearance of the RE texture component and a significant increase in texture intensity.

Summary: An improved thermomechanical treatment (N-ITMT) with electrically-assisted recrystallization annealing (EARA) was proposed for manufacturing fine-grained Al-Cu-Li alloys. The combination of electric current and coarse precipitates completed the recrystallization and solution process in a short time, refining the grain size and improving the strength and ductility. The proposed N-ITMT containing EARA possesses the capability of optimizing the microstructure and enhancing the mechanical properties of Al-Cu-Li alloys.

Summary: Deformation twinning in body-centered cubic (BCC) metals occurs by shearing the crystal along specific planes, and recent studies have shown that antitwinning shear can lead to twinning in some BCC metals. Molecular statics simulations reveal that twinning can occur on both twinning and antitwinning shear in transition metals, but only on twinning shear in alpha-Fe and alkali metals. TEM diffraction pattern analyses further confirm the existence of regular twins along antitwinning shear in Nb and Cr, and exclusively on twinning shear in alpha-Fe.

Summary: The computer-aided development of the leveling technology for high-strength steel flat sheet products is the primary focus of this research. A reliable hardening model is developed based on experimental and numerical investigation, using an inverse analysis approach for parameter identification. The roll leveling process for various machine setups is simulated using a finite element model, and the results in terms of final flatness and stress distributions are presented. A set of process parameters that meet both criteria is identified, ensuring a high-quality product.

Summary: The objective of this article is to develop descriptors of multiphase microstructure for comparing the local fracture resistance of materials. The study proposes a hypothesis that local gradients of properties can represent the tendency to local fracture and can be an effective indicator for stretch-flangeability properties. A novel gradient evaluation algorithm is developed, and it is applied to two different steel samples with different parameter setups. The results demonstrate that this method is effective and reliable for comparing materials' stretch-flangeability.

Summary: The evolution of metallic material microstructures under thermomechanical treatment has a significant impact on the in-use properties of the final product. In recent years, methods that explicitly represent morphological elements have been increasingly used in static recrystallization (SRX) modeling. This article reviews the progress and capabilities of cellular automata (CA)-based full-field SRX models, highlighting various mechanisms controlling microstructure evolution, such as energy distribution, nucleation, grain growth, and grain boundary migration. The article also addresses the computational time issue associated with 3D CA modeling and evaluates possible approaches for reducing simulation times.

Summary: The fracture toughness of low-carbon bainitic steel after a continuous cooling process was investigated using the J-integral approach. The study focused on determining the microstructural factors that influence the fracture processes, including crystallographic units, phase dimensions, and morphology. The results showed that the fracture surface exhibited complex fracture mechanisms, such as quasi-cleavage, transcrystalline cleavage-ductile, and ductile mode. The cracking processes were mainly influenced by bainitic ferrite packets and prior austenite grain boundaries. Changes in the crack path direction were associated with changes in misorientation angles, with the most significant changes occurring in the bainitic ferrite packets. The study also identified a fracture process zone induced by the crack tip, where blocky austenite transformed into brittle martensite due to its high carbon content. Microcracks were nucleated from the transformed martensite and M/A constituents in the initial microstructure. The reduced dislocation density in the bainitic ferrite, caused by the formation of sub-grains, was observed in the crack tip area. Finally, potential improvements in the fracture toughness of bainitic steels were determined.

Summary: We have developed a 3D scanning and rapid prototyping-based approach to design high precision, single pass tube drawing technology for the production of high-quality internally helically ribbed tubes. The main challenge in the existing process design is to determine the stability criterion of the floating plug for manufacturing high precision helical ribs. The novelty of our approach lies in using a combination of 3D scanning and rapid prototyping processes to design a complex floating plug geometry based on minimizing membrane energy, along with computer-aided design of drawing die geometry and process parameters.

Summary: Full-field simulations require high-quality initial digital material representation (DMR) data to improve the predictability of classical finite element models. An unconstrained grain growth algorithm based on the random cellular automata (RCA) method can provide high-quality DMR. This study develops and benchmarks four neighbor-search algorithms for the RCA method, evaluating their complexity and impact on computational efficiency. The results show that significantly reducing RCA simulation time is possible with optimized neighbor-search algorithms and problem-specific code optimizations.

Summary: This study focuses on manganese doped CdS thin films synthesized by chemical bath deposition. The incorporation of Mn2+ cations in CdS was found to influence the crystalline structure, morphology, and optoelectronic properties. Doped thin films exhibited a uniform hexagonal structure, changed growth orientation, and showed scale-like and needle-like morphologies. The bandgap and rectification speed of Schottky diodes were modified by introducing manganese. This study suggests the potential for affordable high-speed optoelectronic devices.

The results show that the hybrid composite produced by hot cross rolling exhibits better corrosion resistance compared to the base metal. The addition of a small amount of graphite improves the bonding between the matrix and reinforcements, and the hot cross rolling enhances this bonding, leading to the formation of a strong passivation oxide layer and increased charge transfer resistance, thereby improving corrosion resistance.
