Summary: The study investigated the dynamic recrystallization mechanism of the Ti-48Al-2Cr-2Nb alloy during thermal uniaxial compression experiments. It was found that both discontinuous dynamic recrystallization (DDRX) and continuous dynamic recrystallization (CDRX) occurred in the gamma grains, with the crystal orientations of CDRX grains close to the (001) orientation at a strain of 0.92. The emergence of DRX in the gamma laths of lamellar colonies and the alpha 2 to gamma phase transformation were confirmed, and a new hot processing map based on DRX volume fraction was established to optimize the thermo-mechanical treatment of the TiAl alloy.

Summary: This paper investigates the hot working properties of Ti-6554 alloy. Hot compression experiments were conducted in a temperature range of 680 to 830°C and a strain rate range of 0.001 to 10 s-1. The hot workability of the alloy was analyzed based on the hot processing map and microstructure evolution. The results revealed that the thermal activation energy was higher at higher strain rates, and the average thermal activation energy decreased with increasing strain. The peak efficiency in the hot processing map was observed at specific temperature and strain rate conditions. The instability regions were concentrated at higher strain rates, and flow localization was observed as a typical instability phenomenon. The volume fraction and average size of the alpha phase decreased due to the dynamic phase transformation with increasing strain rate and temperature. The deformation mechanism transitioned from dynamic recovery to dynamic recrystallization. The types of dynamic recrystallization for the beta phase were identified as discontinuous and continuous, depending on temperature and strain rate. Additionally, the spheroidization mechanism of the equiaxed alpha phase was analyzed. The aspect ratio of the equiaxed alpha phase increased under compressive stress, transforming into lamellar alpha phase. The low angle grain boundaries gradually transformed into high angle grain boundaries with wedging of the beta phase, resulting in spheroidization.

Summary: This study utilized transmission electron microscopy to investigate the hot deformation behavior of a beta-solidifying gamma-TiAl alloy with a duplex structure. It found that twinning is closely linked to twin intersections in gamma grains. As isothermal compression proceeded, faults evolved into twins, with dislocations aiding in promoting twinning in gamma grains.

Summary: This study investigated the strengthening mechanisms of as-cast CrMoNbTiW BCC refractory high entropy alloy, finding that solid solution strengthening is the dominant mechanism. The predicted yield strength at high temperatures is significantly affected by temperature-dependent material constants, with the absolute value depending on the shear modulus and the variation with temperature influenced by Poisson's ratio. It was also shown that high temperature yield strength can be predicted using material constants from literature.

Summary: Macroscopic shear bands (MSB) may form during hot working of metallic materials. The microstructural transitions between the onset of flow instability and MSB inception are not fully understood. In this study, aluminum alloy specimens were tested at different temperatures and it was found that MSB only appeared at a certain level of deformation. The formation of MSB was explained by the development of clusters of severely deforming grains and the differential dynamic recovery between hard- and soft-oriented grains.

Summary: Metastable beta Ti alloys based on the Ti-Nb system have attracted attention due to their unique properties. However, the unstable cyclic behavior of these alloys has hindered their widespread industrial use. Recent studies have shown that internal stresses, including those from dislocations, may be responsible for this behavior. This study demonstrates that inter-cycle thermal treatments can mitigate the unstable cyclic behavior, providing a significant breakthrough in our understanding of Ti-Nb superelastic materials.

Summary: This paper systematically investigated the evolution of microstructure in Fe-Ni-Co-Al polycrystalline alloys and its effects on mechanical properties. The results revealed that the migration of grain boundaries in different processes is driven by different factors, which impacts the grain orientation and precipitate formation. In the process of directional recrystallization, grains with specific orientations grow in the grain boundary region and form the dominant orientation, while grains with lower migration rate form the minor orientation. The alloy produced through directional recrystallization exhibited good recoverable strain and superelastic strain, while the alloy produced through solid solution treatment showed no evident superelastic behavior.

Summary: This study employed laser metal deposition to additively manufacture Ti-15Mo wt% alloy, and subsequently subjected it to post-fabrication uniaxial thermomechanical processing. The results showed that different zones in the microstructure remained after processing, and deformation mechanisms mainly involved slip and martensite formation. The compressive mechanical properties were found to be dependent on strain rate, with higher flow stress and compressive strength observed at higher strain rates. Grain structure homogenisation was not achieved, leading to anisotropic tensile properties.

Summary: This study examines the effect of Cr additions on the mechanical behavior of TWIP steel at temperatures ranging from 25°C to 350°C. The results indicate that different temperature-dependent strengthening mechanisms, including mechanical twinning, Dynamic Strain Aging, and slip bands, are at play. The stacking fault energy (SFE) influences the percentage of mechanical twinning, which in turn affects the strain hardening rate.

Summary: The mechanical properties and microstructural evolution of C-doped TRIP-assisted HEA under dynamic loading conditions were systematically investigated in this study. The results showed that dynamic tensile deformation led to an increase in yield strength and a decrease in ultimate tensile strength, with a trend towards increased total elongation. The primary deformation mechanisms shifted from TRIP and TWIP effects to deformation twinning and dislocations. The presence of carbides formed through C-doping hindered dislocation slip and promoted the activation of multiple twinning systems.
