Revealing the early electrochemical corrosion behavior of Mg–Zn–Zr-Nd alloys in a simulated orthopedic environment by Changhong Cai, Chao Yu, Maryna G. Taryba, Marta M. Alves, Renbo Song, Yan Cui, M. Fátima Montemor

“…However, the film cannot provide a stable protection in the initial stage: its destruction and reconstruction are monitored at around 12 and 20 h, while corrosion current densities are gradually reduced and eventually fluctuate at about 5 μA cm−2. The microstructure, corrosion products, and corrosion activity evolution are interrelated and jointly affect the early electrochemical corrosion behavior of Mg–2Zn-0.6Zr-xNd alloy in a simulated orthopedic environment, among which the Mg–2Zn-0.6Zr-1.0Nd alloy exhibit better performance for the proposed application.…”

Femtosecond laser shock peening of ultra-thin-walled Ti-6Al-4V: study on surface integrity and high cycle fatigue mechanism by Rongping Wang, Xinbin Zhang, Peng He, Wenhe Wang, Wenhua Chen, Xiaolong Wei, Xinlei Pan, Liucheng Zhou

“…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. …”
