Summary: Lightweight austenitic steels have the potential to reduce CO2 emissions and improve fuel efficiency in the automotive sector. This study investigated the recrystallization behavior of cold rolled Fe-30Mn-5Al-1C-(0-3wt%)Mo austenitic steels after annealing at 600-1200℃ through various analytical techniques. The addition of Mo increased the recrystallization temperature and led to the precipitation of M2C carbides, resulting in grain refinement and delayed recrystallization. Hardness was also affected by Mo content and annealing temperature, with all alloys exhibiting similar grain size and hardness at 1200℃ due to grain growth.

Summary: This study investigates the influence of copper foil thickness on the mechanical properties from the perspective of crystallographic microstructure. Two electroplating methods are proposed to enhance the mechanical properties of copper foils by forming multilayer laminated structures. Cycling between electroplating solutions with different additive concentrations or modulating the current density can control the recrystallization behavior and improve the mechanical properties.

Summary: The recrystallization behavior of cold-rolled (85%) Cu-Cr-Nb-Zr alloy was investigated using differential scanning calorimetry (DSC), hardness test, optical microscopy, and electron backscattered diffraction (EBSD). The activation energy for recrystallization ranged from 209-226 kJ mol(-1), as determined by analyzing DSC thermograms using the Kissinger, Boswell, and Ozawa methods. The recrystallization temperature was found to increase linearly with heating rate (10-40 degrees C min(-1)) based on sigmoidal curves fitted to the recrystallization fraction obtained from DSC analysis. The results from DSC analysis were validated through comparison with grain orientation spread (GOS) maps and hardness tests, showing good agreement among the three methods.

Summary: This study investigates the plastic strain distribution of cold spray Cu powders and coatings using electron backscatter diffraction (EBSD) analysis. It is found that more dynamic recrystallization and plastic strain release occur in the as-sprayed EP and GA coatings compared to the WA coating. The influence of recrystallization of twin grains in the GA coating on the ductility of the coating is discussed. The static recrystallization in the postannealing treatment is more prominent in the EP and GA coatings, supporting differences in dynamic recrystallization among the cold-sprayed coatings determined through EBSD analysis. The thermal conductivity of cold-sprayed Cu coatings is affected by recrystallization and strain release.

Summary: When cold spraying is performed at a velocity equivalent to or greater than a material-dependent critical velocity, powders undergo plastic deformation and localized heating, leading to metallurgical bonding and/or mechanical interlocking. This study examined the characteristics of Cu feedstocks and their influence on the bonding strength of cold-sprayed Cu coatings. The results showed that annealing released plastic microstrains in Cu powders, and feedstock properties affected the resulting coating's ductility and hardness.

Summary: The hot deformation behavior of a spray-formed 2195 aluminum-lithium alloy is studied using advanced physical simulation technology and systematic characterization methods. An improved isothermal processing map is constructed to capture the deformation features under continuously varying strain. The DRX 'C-curve' model is proposed to analyze the microstructure evolution. The results show tendencies of discontinuous dynamic recrystallization (DDRX) at low temperatures and continuous dynamic recrystallization (CDRX) at high temperatures.

Summary: This research studied the relationship between processing and microstructure in cold sprayed AA7050 after laser heat treatment with different levels of heat input. The ability to modify the microstructure and properties of cold sprayed AA7050 using laser heating is important for repair applications. A diode laser was used to heat treat the cold sprayed AA7050 in situ, without sectioning samples. The results showed that laser heat treatment coarsened the ultra-fine grains in the deposit's particle boundary regions, while the larger grains in the particle center regions remained the same. Precipitates were observed in the deposits after laser heat treatment, and the highest heat input deposit had the highest density of precipitates.

Summary: The geological disposal system in Japan involves containing vitrified waste in a metal overpack surrounded by a bentonite buffer to prevent contact with groundwater for at least 1,000 years. Despite steel being traditionally chosen for the overpack, advancements in copper corrosion and manufacturing technologies have led to consideration of other materials like copper. The focus is now on investigating the applicability of copper-coating technologies for long-term containment with low manufacturing costs.

Summary: In situ U-Pb radiometric dating of zircons is a widely used method to determine geochronologic ages, but recent studies suggest that radiogenic Pb mobilization within zircon may lead to inaccurate age determinations with unknown geological significance. This study investigated Pb mobilization in shock metamorphosed lunar zircons, revealing heterogeneous distribution of radiogenic Pb within single grains and potential impact of shock-related deformation on Pb* migration. The results imply that large errors in U-Pb ages could obscure reverse discordance and bias the oldest Pb-207/Pb-206 ages to older values, or be explained by mixing of Pb-retention and Pb-loss nanodomains.

Summary: This study investigates the influence of He-V complexes on H behaviors on different W surfaces using DFT calculations. The results show that H dissolution is most difficult but H trapping is easiest on the W (110) surface, while the opposite is true on the W (111) surface. Moreover, the presence of He-V complexes increases the difficulty of H diffusion from bulk to surface and desorption.

A reaction kinetics model is established and computational fluid dynamics with a dynamic mesh method is used to simulate the oxidation process. The results show that the geometric shape of graphite changes significantly with increasing flow rate, and the graphite pebbles tend to form a structure with a narrow front and wide tail.

Summary: This study proposes a probabilistic and diffusion-based model to describe the co-deposition of multiple hydrogen isotopes with slowly grown metal layers. The model calculates the relative concentrations of different hydrogen isotopes in the co-deposited metal layers. It is found that if hydrogen isotopes have different detrapping energies, only the isotope with the highest detrapping energy shows a monotonic decrease in concentration with deposition temperature. Furthermore, the study evaluates the uncertainty of tritium concentration in the co-deposited layer based on the uncertainty in detrapping energy of tritium and deuterium, predicting a >10% tritium concentration uncertainty for a 0.01 eV difference.
