Summary: The experiment showed that SiC fibers with scheelite coating treated in vacuum exhibited good thermal stability, while fibers prepared in Ar/air had significantly degraded strength and poor spool ability. This difference is attributed to the assisted oxidation of SiC fiber by calcium salts in Ar/air atmosphere.

Summary: CrTaN coatings have gained increasing interest as suitable materials for metal cutting applications due to their combination of high hardness and increased fracture toughness. However, the mechanisms underlying the oxidation of this coating system are not thoroughly understood. This study revealed that CrTaN coatings exhibit excellent oxidation resistance up to approximately 1050 degrees C, where the formation of CrTaO4 and Cr2O3 compounds occurs. At 1225 degrees C, the structure evolution of the CrTaN coating includes intact fcc-CrTaN regions near the substrate, a porous intermediate layer of r-Cr2O3 and t-CrTaO4, and a dense r-Cr2O3 oxide scale at the surface.

Summary: Surrogate tristructural-isotropic (TRISO)-coated fuel particles were oxidized in 0.2 kPa O-2 to examine the behavior of the SiC layer. The analysis of the resulting SiO2 layers showed a majority of smooth, amorphous SiO2 with a constant thickness indicative of passive oxidation. The activation energy for oxide growth was consistent across all temperatures and the presence of irregular grain size influenced the oxidation response of the SiC layer.

Summary: Polysiloxane (PSO) was used as the matrix and SiC-ZrB2 powder as the filler to repair prefabricated defects on the SiC-ZrB2/SiC coating of carbon/carbon (C/C) composites. Different treatment processes were applied to investigate their effects on the repair agents' chemical composition, microstructure, and oxidation resistance behavior. Both processes resulted in pyrolysis and the generation of SiOC ceramics, which were well combined with the original coating. The repaired coatings showed improved thermal stability and oxidation resistance compared to the unrepaired coating, providing an effective and simple approach for repairing damaged coatings in high-temperature applications.

Summary: This study investigated the high cycle fatigue properties and microstructural characteristics of submicron-grained Nb + Ti stabilized low C steel processed through advanced multiphase-controlled rolling and multiaxial forging. The research found that the forged specimens exhibited significantly improved fatigue strength compared to untreated annealed steel, attributed to the formation of nano-sized fragmented cementite particles in the ferritic matrix. Superior mechanical properties and high fatigue resistance make the SG material ideal for high-strength structural applications.

Summary: The use of AlSi alloy as a dissipative agent in graphite matrix to create AlSi/graphite composites improved ablation resistance by dissipating heat and oxygen, but the resistance decreased over time due to the continuous consumption of the AlSi alloy during ablation. Heat dissipation played an increasingly significant role in enhancing ablation resistance from 10.1% at 10 seconds to 62.1% at 60 seconds.

Summary: The present study investigates the tensile deformation behavior of a coarse-grained cast alloy 625 using empirical and physics-based models. Experimental stress-strain data showed that the alloy's flow stress curve deviates significantly from the traditional Holloman equation. Additionally, a distinctive hump is observed in the strain-hardening curve. A dislocation density-based phenomenological model is used to understand the mechanisms governing plastic deformation, and the hump in the strain-hardening curve is attributed to the low-stacking fault energy and large grain size of the material. Microstructural studies confirmed the transition in slip activity, and it was found that increasing deformation temperature enhances the rate of dynamic recovery and the rate of single- -> multiple-slip transition. The study also highlights the importance of carbide/matrix and carbide/grain boundary interfaces in crack nucleation and propagation during deformation.

Summary: This study investigated the impact of thermomechanical processing and coiling temperature on various strengthening mechanisms in a low carbon Nb + V microalloyed steel. The research found that within the coiling temperature range of 650-550 degrees C, the pro-eutectoid ferrite + pearlite phase mixture resulted in sufficient ductility and strength. At a coiling temperature of 500 degrees C, the strength-ductility combination remained relatively unchanged, although a small amount of Widmanstatten ferrite was formed. Isothermal holding led to the formation of niobium and vanadium-rich fine carbides.

Summary: AA5xxx alloys are commonly used for marine appliances, but they are not suitable for high-strength marine parts due to their low mechanical strength. This study focuses on developing fine-grained AA5083 nanocomposites reinforced with nanosize SiC particles to improve their performance for high-strength marine components. Stir casting and friction stir processing (FSP) were used to produce the nanocomposites and modify their microstructure. The FSP resulted in the evolution of fine recrystallized grains with a uniform distribution of nanosize SiC particles, leading to enhanced mechanical properties. The strength of the nanocomposites was found to improve up to 2 wt% reinforcement.

Summary: The effects of titanium (Ti) and titanium+aluminium (Al) addition on the thermal stability and mechanical behaviour of Fe-42 wt% Ni-2 wt% Y2O3-X (X = Ti, Ti+Al) alloys were investigated in this study. Fe-42 wt% Ni-2 wt% Y2O3-2 wt% Ti (2Ti) and Fe-42 wt% Ni-2 wt% Y2O3-2 wt% Ti-2 wt% Al (2AlTi) compositions were prepared through mechanical alloying and spark plasma sintering. The 2AlTi alloy exhibited smaller grain size and superior mechanical properties compared to the 2Ti alloy. Grain boundary hardening and dispersion strengthening were identified as the main strengthening mechanisms in the 2AlTi alloy.

Summary: Refractory metal based alloys have great potential as structural materials for high-temperature applications due to their high melting points. However, they are prone to catastrophic oxidation at around 700 degrees C. This study investigated the effect of aluminium diffusion coatings on the oxidation resistance of pure molybdenum, niobium, tantalum, and tungsten. The results showed that the aluminization improved the oxidation behavior and decreased the oxide growth rate for molybdenum and tantalum.
