Femtosecond laser shock peening of ultra-thin-walled Ti-6Al-4V: study on surface integrity and high cycle fatigue mechanism
Published 2025-07-01“…This improvement is attributed to the generation of a high-amplitude compressive residual stress (CRS) layer approximately 100 μm deep at the surface. Microstructural evolution and dislocation behavior analysis revealed that a single femtosecond laser shock peening (FS-1) significantly refined the grain structure and increased dislocation density, while triple femtosecond laser shock peening (FS-3) reduced dislocation density through a dynamic recrystallization (DRX) recovery mechanism. …”

A Multi-Scale Investigation of Sandy Red Clay Degradation Mechanisms During Wet–Dry Cycles and Their Implications for Slope Stability
Published 2025-04-01“…Concurrently, the relative expansion rate (<i>δ<sub>r</sub></i>) and relative shrinkage rate (<i>η<sub>r</sub></i>) gradually declined. (2) At the microscale, wet–dry cycles induced significant changes in the microstructure, characterized by increased particle rounding, disrupted stacked aggregates, altered inter-particle contacts, enlarged and interconnected pores, increased number of pores, and a reduction in clay mineral content. (3) At the mesoscale, cracks initiated and propagated. …”
