Summary: This study investigated the mechanical properties of alkali-activated concrete (AAC) exposed to cryogenic temperatures as low as -160 degrees C. The results showed that the mechanical properties of AAC significantly improved as the temperature decreased. AAC with lower strength grades was more susceptible to low temperatures due to its high moisture content and water-accessible porosity. Compared to ordinary Portland cement-based concrete (OPCC), AAC exhibited superior mechanical characteristics at comparable temperatures. Empirical relations were proposed to correlate the mechanical performances of AAC and temperatures based on the test data.

Summary: In this study, indentation tests were performed on the surface of an interstitial high-entropy alloy to investigate the effects of ultrasonic surface mechanical attrition treatment and thermal aging treatment. The results show that the mechanical behavior of the alloy is significantly influenced by these two treatments. X-ray diffraction and electron backscatter diffraction techniques were used to analyze the changes in microscopic morphology, grain size, phase structure, etc. The study also revealed the microstructure evolution mechanism of the alloy under long-term high temperature conditions.

Summary: Surface mechanical alloying with Si powder on Al can create surface composites with improved dielectric properties compared to coarse-grained and annealed Al composites. The composite containing Al-Si solid solution exhibits frequency-dependent behavior for dielectric constant, dielectric loss, and capacitance in a voltage range of 0.1 to 0.5 V at room temperature. Increasing Si content in the surface composite leads to an increase in dielectric constant, tan delta, and capacitance due to the formation of solid solutions between Al and Si. The severe plastic deformed microstructure of the Al electrode plays an important role in controlling the dielectric properties of the Al surface containing Al-Si composite. © 2023 Elsevier B.V.

Summary: The incorporation of metakaolin improves the workability and mechanical properties of magnesium phosphate cement (MPC) and extends its setting time. It enhances the static and dynamic mechanical properties of MPC at high temperatures and improves its impact resistance. The main hydration products of MPC with metakaolin are struvite, unreacted MgO, aluminum phosphate, and possibly amorphous substance containing aluminum.

Summary: This study found that the optimal pretreatment temperature for energycane bagasse is 170 degrees Celsius, with significantly less inhibitor production below this temperature and an exponential increase in total inhibitor production beyond it. Biomass solids loading has a significant effect on inhibitor generation at higher pretreatment temperatures, with concentrations of certain inhibitors increasing more than threefold on doubling the solids loading. Additionally, a novel low-severity approach combining low-temperature hydrothermal pretreatment with cryogenic grinding has been introduced to improve sugar yields while keeping inhibitor concentrations low.

Summary: The three-step process of solution treatment, stretching deformation at cryogenic temperature, and artificial aging treatment is a potential route for fabricating complex shaped thin-walled components of aluminum alloy. Cryogenic stretching deformation in 2060 Al-Li alloy led to increased T-1 phase nucleation sites, resulting in a markedly homogeneous distribution and optimized after-aging mechanical properties with high strength. High ductility was maintained due to the alloy's high homogeneous deformation ability at cryogenic temperature.

Summary: The study investigates the effect of cryogenic treatment on the microstructure, retained austenite evolution, and mechanical properties of 55Cr17Mo1VN plastic die steel. Cryogenic treatment decreased RA volume fraction and increased hardness by increasing dislocation density, leading to improved steel stability. The treatment also decreased thermal stability of RA phase during tempering, resulting in precipitation strengthening, fine grain strengthening, and dislocation strengthening for improved tensile strength and hardness.

Summary: This study investigates the mechanical properties of frozen soil under different freezing temperatures and examines the effects of temperature and time on freezing depth. A mechanical model for frozen soil breaking under blasting stress wave is proposed, and the theoretical formula for fracture length is deduced. The results show linear frozen depth curves at different temperatures, with lower temperature indicating greater early freezing rate. Additionally, the strength and cohesion of frozen soil decrease with temperature, while shear strength, friction angle, and other factors exhibit a non-linear relationship.

Summary: The evolution of heterogeneous microstructure and mechanical properties of a 12Cr-10Ni-Mo-Ti maraging steel was studied at different aging temperatures. The study found that as the aging temperature increases, more reversed austenite forms and more lath-like reversed austenite coalesces together, leading to the formation of a martensite and austenite dual-phase microstructure. Fine eta-Ni-3(Ti, Al) particles initially precipitate at 440 degrees C and grow with increased aging temperature, but coarsen and dissolve as the aging temperature further increases. The desirable heterogeneous microstructure at 500 degrees C contributes to high yield strength and reasonable cryogenic impact toughness.
