As-cast microstructure characteristics of K439B nickel-based superalloy thin- walled castings of different thickness
Published 2025-01-01“…For this purpose, the thin-wall castings with wall thicknesses of 1 mm and 2 mm are designed, and gravity investment casting experiments and numerical simulations are conducted. Comparative analysis of the as-cast microstructure of the castings shows that the growth directions of the dendrites in both 1 mm and 2 mm thin-wall are along the shell wall pointing to the center, the difference is that the growth directions of the dendrites in the 1 mm thin-wall are closer to the vertical angle with the wall. …”

Cognitive implications of white matter microstructural changes in individuals with low heart rate variability: a NODDI study
Published 2025-05-01“…The extracted values from these ROIs (p < 0.05) were mainly manifested in the anterior regions of the brain and corpus callosum. Further analysis showed that the abnormal white matter (WM) showed significant correlations with CDR, RCFT-I, RCFT-D, attention, memory, language, and cognition-related plasma biomarkers to varying degrees.ConclusionPatients with low HRV exhibit distinctive patterns of microstructural changes in the WM as revealed by the FISO which indicate a decline in white matter integrity, and the relationship between low HRV-related and worse cognitive performance may be attributed to damage of the frontal-corpus callosum pathways.…”

Effect of Deposition Conditions on Microstructure and Composition of Nitride Monolayer and Carbide-Nitride Multilayer Coatings Based on W and Nb
Published 2025-06-01“…The effects of substrate bias voltage (–50 V to –200 V) and cathode arc current (130 – 150 A for W, 110 – 120 A for Nb) were systematically studied to tailor coating morphology, phase formation, and elemental distribution. Cross-sectional microstructural analysis revealed pseudo-multilayer structures within monolayers due to substrate rotation and limited interdiffusion. …”
