Anisotropy in single-crystal properties of polycrystals controls both the overall response aggregates and patterning local stress/strain distributions, extremes which govern failure processes. Improving understanding grain-grain interactions has important consequences for in-service performance limits. Three-dimensional synchrotron X-ray diffraction was used to study evolution grain-resolved stresses over many contiguous grains Zr Ti deformed situ. In a significant fraction grains, stress...
In this work we combine experiments and simulations to study the residual deformation state near twins in titanium at different stages of complete twin growth process, including tip: (i) far from a grain boundary, (ii) approaching (iii) intersecting with boundary. High resolution electron backscatter diffraction (HR-EBSD) was used characterise local stress dislocation density distributions. Schmid factors were calculated both global (i.e. remote loading) high angular EBSD). Crystal...
Attaining substantial areal capacity (>3 mAh/cm2) and extended cycle longevity in all-solid-state lithium metal batteries necessitates the implementation of solid-state electrolytes (SSEs) capable withstanding elevated critical current densities capacities. In this study, we report a high-performing vacancy-rich Li9N2Cl3 SSE demonstrating excellent compatibility atmospheric stability enabling high-areal capacity, long-lasting batteries. The facilitates efficient lithium-ion transport due to...
Stress fields close to twin tips and the associated local neighbourhoods of a hexagonal close-packed (HCP) polycrystal were studied in detail. For this purpose, coarse grain textured Zircaloy-2 sample was firstly strained uniaxially macroscopic direction that favours tensile formation. The then unloaded residual elastic strains lattice rotations measured using high-resolution electron backscatter diffraction (HR-EBSD) technique. Measured strain maps various clusters grains including parent...
The effects of reorientation and twin shear transfer on the load sharing between parent pairs in hexagonal closed-pack (HCP) polycrystals have been examined by combined experimental numerical methods. A highly textured Zircaloy-2 sample was uniaxially strained a direction that favours formation then unloaded to measure variations residual elastic strains, lattice rotations, stresses within grains use high resolution electron backscattered diffraction (HR-EBSD). measured grain structures were...
