Summary: The study investigates the strength, durability, and corrosion resistance of quaternary blended mortar made with PPC, GGBS, and RHA in a marine environment. The optimized quaternary blended mortar exhibits improved mechanical strengths and enhanced resistance to chloride penetration, corrosion, and water absorption compared to the control mix after exposure to marine environment. Mineralogical and chemical analyses are conducted to determine the effects of marine environment exposure on the different mixes.

Summary: Ti2AlNb alloy is a new lightweight and heat-resistant structural material with improved mechanical properties. Laser shock peening (LSP) was used to investigate the microstructure response of different phases in the alloy. The study found that the highest density of dislocations was generated in the B2/beta phases, followed by the O phases, and the least dislocations were observed in the alpha 2 phases. Dislocation structures, stacking faults, mechanical twins, and dislocation cells were observed, which contributed to the refinement of the microstructure and improved hardness and residual stress distribution.

Summary: The study analyzed the performance of stainless steel 316 as a containment material for phase change material (PCM) cycled at high temperatures using X-ray photoelectron spectroscopy and X-ray diffraction methods. Increasing exposure time to PCM was found to lead to increased oxidation and depletion, resulting in embrittlement of the sigma-phase structure in the corrosion layer.

Summary: The effects of Bi additions on the properties of Sn-2Cu solder alloy were investigated. The addition of 5 wt% Bi improved the thermal properties, refined the microstructure, and increased the microhardness and tensile strength. Additionally, a dense passivation film formed on the alloy surface, providing excellent corrosion resistance.

Summary: This study investigated the effect of yttrium and neodymium alloying on microstructure formation during severe plastic deformation and its impact on the mechanical and corrosion properties of binary Mg-3Y and Mg-3Nd alloys. The presence of Nd primarily caused precipitation, while Y remained dissolved in the magnesium matrix. The ECAP-processed W3 sample exhibited a combination of ultrafine-grain structure, weak crystallographic texture, high strength, and high corrosion resistance.

Summary: The thermal shock resistance of silicon nitride was studied using a water quenching method, and the differences in residual strength after thermal shock were analyzed. The results showed that the surface layer of the samples changed with increasing heat treatment temperature, forming a darker subsurface layer, in which more small pores were found and played a role in dissipating thermal stress. However, this subsurface layer disappeared during natural cooling, leading to the formation of large cracks on the surface layer.

Summary: This research analyzed and determined the changes in the mechanical characteristics of granites after various thermal shocks through a comprehensive review of research. The change mechanisms of the mechanical responses of granites after various thermal shocks were revealed by microstructural observations. The macroscale deterioration of the mechanical parameters of various granites after thermal shocks is closely associated with the initiation, development, and coalescence of microcracks.

Summary: The lightweight alumina aggregates were used to partially replace traditional tabular alumina aggregates in the preparation of lightweight Al2O3-MgO-C refractories for steel ladle linings. The addition of lightweight alumina aggregates improved the strength, thermal shock resistance, and slag corrosion resistance of the refractories. These improvements were due to the optimized interface bonding between aggregates and matrix, the reduced thermal expansion coefficient, and the formation of a protective layer and densified matrix.

Summary: A developed tungsten grade with high strength and great plasticity was prepared through powder metallurgy technology and low-temperature rolling. The material exhibited excellent tensile properties, with a high ductile-brittle transition temperature and high ultimate tensile strength. It also showed outstanding transient thermal shock resistance, with the ability to withstand high absorbed power densities without surface damages or cracks. This work is important for establishing a reliable data-library for a unitary tungsten grade in China Fusion Engineering Test Reactor (CFETR) and can provide valuable insights for material performance identification and subsequent numerical simulations.

Summary: The effect of doping ceramic reinforcing particles during laser cladding technology has been rarely studied for amorphous alloy coatings. A crack-free Fe-based amorphous/crystalline composite coating with good tribological properties was successfully prepared on the surface of 40Cr steel by varying the content of WC-14Co addition. The addition of WC-14Co particles led to the suppression, disappearance, and reformation of cracks, ultimately achieving a crack-free state at 5 wt% addition.

Summary: The effect of laser shock peening parameters on the corrosion resistance of an E690 high-strength steel cladding layer was investigated. The surface roughness and residual stress were measured, and the microstructure morphology was observed. The electrochemical corrosion tests showed that the corrosion resistance of the cladding layer sample was substantially improved after laser shock treatment.

Summary: This research focuses on the production of silicon carbide foam using slurry and the effect of coating layers and sintering temperature on the microstructure, strength, and thermal shock resistance of the foam. The results showed that multi-layer coating improved the mechanical strength and thermal shock resistivity of the foam, and the optimum strength was obtained in a four-layer coated sample sintered at 1000 degrees C. The study also found that burning off bentonite and silica sol at 1100 degrees C reduced strength and thermal shock resistance.

Summary: The effects of pore size on the electrical and thermal properties of porous SiC ceramics were investigated. It was found that increasing the pore size resulted in higher electrical and thermal conductivities. This can be attributed to the smaller pore/strut interface area in ceramics with larger pore size, reducing the scattering effects and enhancing the conductivities.
