Summary: The mechanical properties and fracture mechanisms of martensitic NiTi shape memory alloy were studied through thermomechanical processing, leading to significant changes in microstructure and differences in plasticity and fracture strength of the alloy. The decrease in plasticity in the annealed alloy is mainly attributed to the reduction of reorientation+detwinning zone and plastic zone, as well as the difference in crack-path configuration resulting in a larger proportion of fracture mode I in the annealed alloy.

Summary: This experiment investigates the effect of TaC addition on the microstructure, densification, and mechanical properties of ZrB2 composites reinforced with graphene nanoplatelets (GNP). The results show that the presence of GNP, alone and combined with TaC, significantly increases the relative density. Full densification is achieved by adding 10 and 20 vol% TaC. ZrB2-GNP and ZrB2-GNP doped with 10 vol% TaC exhibit high flexural strength and fracture toughness.

Summary: Through successive solution treatment, large pre-deformation of 50%, and aging process, the mechanical properties of the 7B52 laminated aluminum alloy were significantly improved. The effects of large pre-deformation on the microstructural evolution and mechanical behavior were examined, with the introduction of dislocations and low-angle grain boundaries being beneficial for precipitation strengthening. The 7A62 alloy exhibited higher strength increments due to its finer grain size, higher dislocation density, and larger number density of precipitates.

Summary: This study investigates the structure and property variation of pressure-induced solid electrolyte interphase (SEI) using molecular dynamics simulations. The results show that pressure promotes SEI structure delamination and reduces porosity, leading to the formation of a thin and dense SEI. Furthermore, the study establishes a phase diagram considering the effects of pressure and salt concentration, which provides guidance for optimizing the mechanical and transport properties of pressure-induced SEI for high-performance lithium metal batteries (LMBs).

Summary: Stretching is an important method for forming polymer films, but the mechanism of stretch-induced structural evolution is still a fundamental issue. Current methods for measuring this process are limited in sampling frequency or materials transparency. In this study, a new principle based on dielectric anisotropy was proposed for measuring the stretching process of polymer materials. The method was successfully applied in measuring tube compliance and dynamic health monitoring, indicating its potential for wide applications.

Summary: This study investigates the calendar aging issue in lithium metal anodes (LMAs) and proposes a method to improve it by controlling the formation of solid-electrolyte interphase (SEI). The results suggest that by controlling the decomposition potential of anions, a stable inorganic anion-derived SEI can be formed, which effectively prolongs the interface failure time and promotes uniform Li deposition, thus reducing chemical corrosion during calendar aging. Additionally, the stable SEI and uniform Li deposition contribute to highly reversible Li plating/stripping, leading to a significantly longer lifespan after calendar aging.
