Summary: The effect of texture evolution, recrystallization behavior, and deformation on the mechanical properties of cold rotary swaged Ti-6Al-4V tubing during annealing was studied. The results showed that the high plasticity of the tubing can be attributed to the combined effect of slip structure and twining structure. After annealing at 750℃, the twinning content decreased significantly, and recrystallization weakened the strengthening effects of dislocations and grain boundaries.

Summary: This study investigated the corrosion performance of super duplex stainless steel specimens under controlled thermal and thermal plus deformation treatments. The best corrosion performance was observed in specimens deformed at around 1100 degrees Celsius, attributed to grain size refinement in the austenite phase. The overall corrosion behavior was found to be controlled by a balance between decreasing austenite fraction and dynamic recrystallization-induced grain size refinement of the austenite phase.

Summary: The effects of temperature and strain rate on the grain orientation and texture of Inconel 617 alloy were analyzed through thermostatic compression experiments. The results showed that DRX in the alloy is influenced by these factors, with discontinuous dynamic recrystallization (DDRX) and continuous dynamic recrystallization (CDRX) events occurring. DRX was found to occur before the peak strain, with a lower critical strain to peak strain ratio due to the influence of twins.

Summary: The temperature damping capacities of Mg-3Al-1Zn-xSn alloys were investigated using a DMA, and the effects of Sn concentration and loading frequency were examined. The addition of Sn resulted in shifts in the damping peaks, indicating the influence of second phases near grain boundaries. The enhanced damping capacity at different frequencies was attributed to increased point defects and precipitates before 220°C, while microplastic internal friction dominated the damping mechanism in the later part of the test.

Summary: This work investigates the hot deformation behavior and microstructure evolution of a non-equimolar TiZrHf-rich refractory high-entropy alloy (RHEA). The study reveals a contradiction between the concentration of group IV elements and high-temperature strength. Excessive addition of group IV elements leads to deterioration of high-temperature strength. The dynamic recrystallization mechanism strongly depends on the thermo-mechanical processing conditions, with a dominant role played by edge dislocations. Stress drops are observed under low deformation temperatures and high strain rates.

Summary: The study investigated the recrystallization behavior of FeCrCuMnNi high entropy alloy after cold deformation, revealing that different phases require different levels of prior cold deformation for recrystallization. An increase in prior cold deformation led to enhanced recrystallized nuclei, indicating the unique characteristics of HEAs may promote this process. Additionally, higher levels of prior cold deformation resulted in a decline in hardness, UTS, and YS after annealing, with changes in fracture mode observed between FCC1 and FCC2 phases.

Summary: The study investigates the microstructure and texture changes of thermomechanically processed 310S austenitic stainless steel. Cryo-rolling with different thickness reductions and subsequent annealing were conducted. Deformation twinning and strain-induced alpha'-martensite were observed after 20% thickness reduction, with higher volume fraction of twinning. With increased deformation, martensite replaced twinning and the volume fraction of martensite increased. Brass, Goss, and S components were dominant textures in the austenite phase, while R-Cu, R-cube, F, and E were the main components in alpha'-martensite. Annealing led to martensite to austenite reversion and recrystallization in the deformed austenite, resulting in increased fractions of Goss and Brass recrystallization components. The annealing texture was similar to the cryo-rolling texture. Martensite reversion was faster at 1223 K for 5 min compared to 1023 K. The optimum annealing temperature for an ultrafine grain structure was found to be 1023 K for 15 min.

Summary: The study revealed that dynamic recrystallization (DRX) behavior was promoted at higher temperatures and lower strain rates, and no 8 phase existed at or above 1333 K deformation temperature. A significant yield drop occurred within the temperature range varying from 1273 K to 1333 K due to the dissolution of the 8 phase and enhanced mobility of defects.

Summary: Shear punch deformation was used to investigate the shear deformation behavior and microstructural evolution of a Mg-Y-Nd-Zr alloy at various temperatures. It was found that metastable phases may precipitate dynamically during deformation, and flow softening behavior was observed at different temperatures. The deformation mode promoted extension twinning, and twinning was observed even at high temperatures. Dynamic recrystallization occurred at 450 and 500 degrees C, with progressive lattice rotation as the mechanism. Shear flow stress was successfully modeled using constitutive equations. The rate-controlling mechanisms were determined to be dislocation glide controlled by rare earth diffusion at 25-400 degrees C and grain boundary sliding controlled by lattice diffusion at 450-500 degrees C.

Summary: In this study, the deformation behavior of a Zn alloy containing 0.2 wt. % magnesium was studied using compression tests at a wide temperature range and different strain rates. The results showed that dynamic recrystallization occurred at all deformation conditions, with continuous dynamic recrystallization (CDRX) being operative through a progressive lattice rotation mechanism. The new grains formed not only around the c-axis, but also around the prismatic and pyramidal poles.

Summary: Rolling is a widely used industrial process to produce various geometries in manufacturing. However, it can lead to anisotropy in the products. This study compares the effects of symmetrical and asymmetrical rolling on an aluminum alloy sheet. The results show that the asymmetrical process produces larger texture gradients and more intense shear texture components, but exhibits lower plastic anisotropy compared to the symmetrical process.

Summary: This research investigates the microstructural and mechanical changes in the welded seam of an austenitic stainless steel tube. The fusion zone experiences the greatest decrease in hardness, followed by the heat-affected zone and the base material. The welding process results in a dendritic structure in the fusion zone and varying austenitic grain sizes from the heat-affected zone to the base material. The mechanical behavior of the seam is influenced by the size of austenite grains, with the larger grains in the fusion zone leading to lower strength and ductility.

Summary: An ultrafine-grained AZ31 Mg alloy processed through multipass equal channel angular pressing (ECAP) achieved mean grain sizes of 5 and 0.9 μm after two and four passes, respectively. Tensile testing at high temperatures revealed that the four-pass-processed alloy exhibited a superplastic elongation of 410% at 250 degrees C. The deformation behavior was studied using the Haehner criterion, showing that grain boundary sliding was the rate-controlling mechanism with a strain rate sensitivity of 0.38. The contribution of slip system to superplasticity was discussed using Schmid factors, which showed that slip activity prevalence at high strains induced texture-strengthening effect and low-angle grain boundary formation.

The results revealed a strong dependence of grain growth activation energy on the deformation processing. The sample ECAP-processed at 350°C exhibited two different values of grain growth activation energy, attributed to the deformation microstructure and dynamic grain growth during ECAP processing at 350°C.

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.
