Such an increase in the heating rate (of zirconium from 2.5 to 7.5°C/min, and of the Zr–1% Nb alloy from 5 to 20°C/min) causes a decrease in the thickness of the ZrO<sub>2</sub> oxide film.

Variations in the chloride ion content and diffusion coefficient under different erosion durations and depths were also investigated. The impact of mineral admixtures on the chloride penetration resistance was explored. Notably, after mixing fly ash (FA) and granulated blast furnace slag (GGBS), the electric flux values of RPC of each group were significantly reduced, and the electric flux values of RPC of the mixed group were significantly lower than those of the single mixed group and the reference group, in which the electric flux of FA10G10 was reduced by 85.2% compared to the control group; at the same erosion cycle and depth, the chloride ion content and diffusion coefficient of the mixed group were significantly lower than the control group. It shows that the reasonable compounding of mineral admixtures can better exert the \"superposition effect\", improve the compactness inside the matrix, and effectively reduce the chloride ion penetration rate.

The most suitable size of NiTi shape memory alloy (nitinol) staples to heal scaphoid fractures was found by comparing two commercially available compression staples (DynaClip™ Bone Fixation System, 10×10 and 14×14 mm). The scaphoid bone was selected for simulating a model in SolidWorks software. To accurately investigate the effect of staple size on the bone the scaphoid was assumed to be a three-layer composite structure consisting of collagen and mineral crystals. The stress distributions along a path located at the waist of the scaphoid were assessed. The finite element analysis was carried out in ABAQUS software based on the nitinol staple shape memory effect and super-elasticity behavior. The results indicated that the smaller size of staples induced a more significant stress on the central zone of the scaphoid, whereas the larger size of staples showed a peak stress concentration on the peripheral zones with a reduced stress concentration at the center.
