Summary: The quasi-static tensile deformation behaviors of Ti-3Al-2Zr-1.5Mo alloy with a lamellar microstructure were studied at room temperature (RT) and 77K. The results showed that the alloy exhibited excellent cryogenic mechanical properties, with higher strength and elongation at 77K compared to RT. The microstructural analysis indicated the presence of a strong cryogenic twinning induced plasticity (TWIP) effect, with the intersection between the substructure and the alpha/beta interface playing a role in twin nucleation at cryogenic temperature. The significant TWIP effect and weakening of interface hindrance on crack propagation contribute to the optimization of the alloy's properties at cryogenic temperature.

Summary: This study investigated the quasi-static tensile deformation behaviors of the CT20 alloy at room temperature and 77 K. The equiaxed microstructure of the CT20 alloy exhibited excellent mechanical properties at cryogenic temperature, with simultaneous increase in strength and elongation. The study also found that cryogenic temperature weakened the deformation texture and promoted multiple slip, resulting in a strong cryogenic twinning-induced plasticity effect. The grain refinement induced a high strain-hardening rate and strength at cryogenic temperature. Furthermore, cryogenic temperature changed the initiation location of cracks and promoted cracks initiation at grain boundaries.

Summary: The tensile behavior of metastable beta-type Ti-15Mo alloy with {332}<113> twinning-induced plasticity (TWIP) effect was investigated at 20K. It was found that the alloy exhibited ultrahigh strength and excellent elongation, making it a major advancement for cryogenic applications. The serrated tensile curve and multiple necking observed were attributed to the formation of twins. The presence of abundant {332}<113> twins and piled-up dislocations at twin boundaries hindered local plastic deformation and necking, resulting in simultaneous enhancement of strength and ductility. Exploiting the {332}<113> TWIP effect in body-centered cubic (BCC) structured titanium alloys is a novel strategy for cryogenic alloy development.

Summary: In this study, a latent and tacky epoxy resin modified with siloxane core-shell particles was developed and investigated for use as a towpreg matrix for winding of cryogenic composite vessels. The mechanical properties, fracture toughness, and plastic zone radius of the modified resin were examined at different temperatures. It was found that the modified resin exhibited improved fracture toughness and reduced plastic zone radius at cryogenic temperatures. The addition of polydimethylsiloxane further enhanced the plastic zone radius, demonstrating the necessity of combinatorial methods in understanding temperature-dependent failure of epoxy matrices.

Summary: The mechanical properties of the (ZrCuNiAl)Tm3 bulk amorphous alloy at cryogenic temperature are significantly dependent on temperature and strain rate, with strain rate softening phenomenon observed under dynamic loading. The compressive strength of the alloy increases significantly with the decrease of temperature under dynamic loading, attributed to the strong interatomic binding force between the alloy elements.

Summary: A criterion has been proposed to predict the phase stability of refractory high-entropy alloys (RHEAs), showing that a small atomic size difference is not a necessary condition for determining the stability of solid solution. The formation of Laves-phase precipitates can be inhibited by decreasing the atomic-size difference, the enthalpy of mixing, and the valence electron concentration. These criteria can be easily adapted to design new RHEAs with the desired phase structure.

Summary: This paper investigates the control of lamellar orientation in alpha-solidified TiAl alloy using anti-gravity investment casting. The macrostructures and microstructures of iso-section plate and variable-section blade are studied in detail. The results show that both the plate and blade body consist of columnar crystals in their macrostructures, while the microstructures are composed of lamellar colonies with preferred orientation and some uncontrolled colonies. The orientation of lamellae between adjacent colonies is almost parallel in the plates, while in the blade body, the angle of lamellae is controlled within 15 degrees. The misorientation between colonies is caused by the tilted growth of alpha dendrites due to the variable-section character of the blade. Additionally, the formation of uncontrolled lamellar colonies is investigated in both plate and blade.

Summary: The study comprehensively investigates the effects of moire-induced lattice distortions on the superlubricity properties of twist MoS2/MoSe2 heterointerfaces through first-principles calculations. The results reveal that lattice distortions lead to localized electronic redistribution and orbital hybridization, resulting in band evolutions. Furthermore, a characteristic moire potential that periodically modulates the sliding energy barrier is observed, and its fluctuation is correlated with changes in interlayer charge density. This study provides essential insights into the nature of moire and superlubricity and paves the way for the development of advanced materials with excellent tribology performance.

Summary: The effect of static magnetic field (SMF) on the interfacial energy of solid Al2Cu and eutectic melt was investigated using the dihedral angle and grain boundary groove methods. It was found experimentally that the solid/liquid interfacial energy varied up to three times with SMF. The interfacial energy showed a decreasing trend with increasing SMF in both methods. The decrease was attributed to thermoelectric magnetic convection at different scales and explained by the magnetic dipole theory and structural ordering based on Ewing's model.

Summary: A systematic study was conducted to understand the microstructure evolution and re-crystallization behavior in a Co-B eutectic alloy under a constant undercooling with respect to the magnetic field intensity. The results revealed that, in the absence of a magnetic field, divorced FCC-Co and Co3B eutectic ellipsoidal grains coexisted with a few regular lamellas. As the magnetic field increased, the primary elongated FCC-Co dendrites and dispersed FCC-Co nanoparticles embedded within the Co3B matrix occupied the inter-dendrite regions. Furthermore, the application of a magnetic field was found to promote recrystallization.

Summary: In this study, ternary Cu52Co24Fe24 immiscible alloys were prepared with varying undercoolings and under a high magnetic field. The microstructure evolution and properties of the alloys were investigated. It was found that the addition of Fe promoted the demixing tendency of the Cu-Co-Fe ternary system during solidification. Under the influence of a high magnetic field, the samples exhibited a more dispersed minority phase, higher microhardness, and improved conductivity.

Summary: The microstructure and properties of a Cu50Co50 immiscible alloy were studied using heat treatment assisted by a magnetic field of 10 T. The results showed that the high magnetic field caused fragmentation and refinement of the Co-rich dendrites in the solid state, while in the semi-solid state, dendrite refinement was due to melting of the outer shell. The coupling effect of Lorentz, TEMF, and TEMC resulted in dendrite fragmentation and growth direction deviation. The hardness of the Cu-rich matrix was improved by the high magnetic field, and the magnetic properties changed due to a decrease in diamagnetic phase contribution and alteration of alloy orientation.
