Summary: High-entropy alloys (HEAs) offer expanded compositional freedom for advanced nuclear applications, but our understanding of their irradiation responses is still in its infancy. While some studies suggest special irradiation damage resistance in HEAs, proposed mechanisms like sluggish diffusion and lattice distortion are not universally convincing, and unique differences in HEAs compared to conventional alloys may lie in factors like poor thermal conductivities.

Summary: Nuclear energy, including nuclear fission and fusion, has complex environmental effects and requires careful consideration. This study examines the relationship between nuclear energy consumption, nuclear reactors, and load capacity factor in eight countries using time-domain and frequency-domain causality tests. The results differ between these tests, with the frequency-domain test revealing causal relationships in the short, intermediate, and long run, while the time-domain test showing no causal relationship. The findings suggest the need for effective policies and investments in nuclear energy and technologies to improve environmental quality.

Summary: This study investigates the variances of the fission fragment mass distributions using the random neck rupture model for symmetric cases. The model excludes crel and generates a more continuous shape for the fissioning nucleus at the boundaries. The empirical formulas obtained for the neck radii predict the mass variances better than the Rayleigh criterion.

Summary: This study examines the feasibility of using Ti as the main strengthening element in the design of precipitation-strengthened alloys, demonstrating the significant role of L1(2)-Al3X-forming elements in enhancing the strength and reducing the susceptibility of aluminium alloys to solidification cracking. By incorporating Si and Ni into the alloy processing, Al-Ti alloys were fabricated, with the Al-2.51Ti-0.7Si alloy reaching a peak hardness of 97HV during heat treatment. This suggests that Si plays a crucial role in enhancing the precipitation process and diffusion of Ti in these alloys.

Summary: The discovery of radioactivity demonstrated that energy in the nucleus can be released as kinetic energy of radioactive particles. Fission and fusion reactions generate large amounts of energy suitable for electricity generation in nuclear power plants. The binding energy associated with each nucleus determines the energy released or absorbed in these nuclear reactions. Nuclear binding energy refers to the energy required to keep protons and neutrons together in a nucleus, while nuclear power is the energy released during nuclear fission or fusion. Each nucleus has its own binding energy, which is equivalent to the energy needed to split the nucleus. The paper presents a web application for calculating nuclear binding energy per nucleon, which involves determining the mass defect and converting it into energy per nucleon.

Summary: The mass and angle distributions for the Cr-52 + Pt-198 and Cr-54 + (19)6Pt reactions forming No-250 were measured and subtracted. The experimental mass distributions unexpectedly extended to symmetric splits, while the peak yield remained close to the initial masses, indicating a strong role of fluctuations in mass division early in the collision. This provides insights into the transition from fast energy dissipative deep-inelastic collisions to quasifission.

Summary: The study reveals that in heavy ion fusion reactions, increasing charge product of colliding nuclei leads to a decrease in the ratio of experimental to computed capture cross sections, while the ratio of sequential fission to capture-fission increases. Experimental results consistently show that the increase in energy dissipation processes correlates with the increase in density overlap at the capture barrier as the charge product of the colliding nuclei increases.

Summary: In this study, 16 different versions of proximity potentials were used to investigate the alpha decay half-lives of 21 possible isotopes around N = Z in the range of 52 ≤ Z ≤ 56. The results showed that the theoretical half-lives of the Prox. 81 and Prox. 88 potential models were in close agreement with experimental data. The study also discussed the variation of the penetration probability of alpha particles and alpha decay half-lives with neutron content based on the isotopic dependence of the Coulomb potential barrier and the released energy. Additionally, the present approaches were compared with other empirical and semi-empirical formulae, and the SemFIS formula was found to have the lowest standard deviation among them for the alpha decay of the studied nuclei.

Summary: This study systematically investigates the lifetimes of quasifission and fusion-fission reactions in heavy ion fusion reactions used in the synthesis of superheavy elements. The DNS model is also used to attempt the synthesis of new superheavy elements. The study shows that the quasifission lifetimes are longer for successful reactions and shorter for unsuccessful reactions. Additionally, the study finds that the fusion-fission lifetimes do not provide any explanation for the failure of experiments to synthesize superheavy elements. It is also observed that the quasifission process can be controlled by selecting projectiles with lightly deformed or spherical nuclei. Furthermore, the study emphasizes the importance of selecting the appropriate projectile-target combination for the synthesis of SHEs with Z = 119 and 120.

Summary: We conducted a systematic study on the widths of fission fragment mass distributions in compound nucleus fission in the pre-actinide region. We analyzed different reaction variables, such as mass asymmetry, ZPZT, N/Z ratio, and excitation energy. The results indicate non-equilibrated fission process or mass asymmetric fission in cases where the mass width shows anomalous behavior with fissioning nuclei excitation energy. The study demonstrates the systematic dependence of the reaction mechanism on entrance channel parameters.

Summary: Competitive continuous and discontinuous precipitation (CP and DP) in magnesium alloys have been studied in-situ for the first time. The migration of the high angle grain boundary (reaction front, RF) behind which DP occurs is found to be irregular instead of steady-state. Local effects play a key role in causing the irregular motion of the RF.

Summary: The study investigated the potential connection between the residual stresses generated by cladding operation, the thermal stresses generated during post weld heat treatment, and the propensity for underclad cracking. Results showed that substantial tensile residual stresses in the heat affected zone persisted after heating to 325 degrees C, but each microstructural zone within the zone may have enough ductility to prevent fracture.

Summary: The initiation mechanism of discontinuous precipitation (DP) reaction in Alloy 33, driven by migrating grain boundaries (GBs) at 800 degrees Celsius, was studied using analytical electron microscopy techniques. The results show that FCC M23C6 is the first phase to precipitate at the GBs, and grain boundary migration is mainly caused by a chemical driving force.

Summary: Pb-Caustic Stress Corrosion Cracking initiation was studied on Alloy 690TT at 315 degrees C. The cracking mainly initiated intergranularly following the oxidation of Cr-rich grain boundary carbides. The as-received surfaces showed higher resistance to crack nucleation compared to polished ones due to the absence of carbide decoration on the grain boundaries in the ultrafine-grained near-surface layer. Dislocation entanglements on the cold-worked surface attenuated the emission of dislocations at the surface. Subsequent cracking was caused by Pb incorporation in the oxide, weakening the passive layer and enhancing slip dissolution.

Summary: The initiation of stress corrosion cracking (SCC) in the filler metal (FM) 82 was investigated in oxygenated water at 288 degrees Celsius. Microstructural analysis after testing revealed the presence of porous oxide incursions at cracked grain boundaries (GBs). Some intergranular cracks also showed oxide along the crack walls, which seemed to form after crack propagation. Similar oxide incursions were observed at the GBs of the non-stressed FM 82 coupon after oxidation for a similar duration. The formation of oxide incursions is discussed, and the evolution of crack initiation is proposed.

Summary: The MEACTOS project aimed to investigate the effectiveness of various surface machining procedures in mitigating environmentally-assisted cracking (EAC) in typical light water reactor structural materials and environments. Tests were conducted on cold-worked (CW) type 316L austenitic stainless steel and nickel-based weld metal Alloy 182 specimens, with different surface treatments applied. Results showed minimal or no significant improvements in EAC initiation susceptibility compared to standard face milling. The stress thresholds for EAC initiation determined in constant load tests were consistent with results from the CERT tests. This paper provides a summary of the key findings and conclusions regarding EAC initiation behavior under PWR and BWR conditions for CW 316L and Alloy 182.

Summary: This work investigates the formation of adjoining twin pairs (ATPs) at grain boundaries (GBs) in hexagonal close-packed (hcp) metals, focusing on the co-nucleation (CN) of pairs of deformation twins. A continuum defect mechanics model is proposed to study the energetic feasibility of CN of ATPs resulting from GB dislocation dissociation. The model reveals that CN is preferred over the nucleation of a single twin variant for low misorientation angle GBs. Further analysis considering GB character and twin system alignment suggests that CN events could be responsible for ATP formation even at low m' values.

Summary: This study investigates the behavior of electric-field induced antiferroelectric to ferroelectric (AFE-FE) phase transition and reveals the evolution of atomic displacement ordering as the cause for the transition behavior changing from sharp to diffuse. The novel semi-ordered configuration results from the competing interaction between long-range displacement modulation and compositional inhomogeneity, which leads to a diffuse AFE-FE transition while maintaining the switching field.

Summary: In this work, a physics-constrained neural network is used to predict grain-level responses in FCC material by incorporating crystal plasticity theory. The key feature, shear strain rate of slip system, is identified based on crystal plasticity and incorporated into the loss function as physical constitutive equations. The introduction of physics constraints accelerates the convergence of the neural network model and improves prediction accuracy, especially for small-scale datasets. Transfer learning is performed to capture complex in-plane deformation of crystals with any initial orientations, including cyclic loading and arbitrary non-monotonic loading.

Summary: This study attempts to address the gap in cooling rates between thin film deposition and bulk metallic glass (BMG) casting by correlating the glass-forming range (GFR) determined from combinatorial materials chips (CMCs) with the glass-forming ability (GFA) of BMG. The results show that the full-width at half maximum (FWHM) of the first sharp diffraction peak (FSDP) is a good indicator of BMG GFA, and strong positive correlations between FWHM and the critical casting diameter (Dmax) are observed in various BMG systems. Furthermore, the Pearson correlation coefficients suggest possible similarities in the GFA natures of certain BMG pairs.
