The mechanical behavior of nanolaminates is dominated by interfaces that act as sources, barriers, and preferred sites for storage dynamic recovery glide dislocations. In this article, the deformation mechanisms a variety metal-based are reviewed with emphasis on unusual properties such ultra-high flow strength without loss plastic deformability.
Volumetric defect types commonly observed in the additively manufactured parts differ their morphologies ascribed to formation mechanisms. Using high-resolution X-ray computed tomography, this study analyzes morphological features of volumetric defects, and statistical distribution, laser powder bed fused Ti-6Al-4V. The geometries three common defects; i.e., lack fusions, gas-entrapped pores, keyholes, are quantified by nine parameters including maximum dimension, roundness, sparseness,...
Light-weight aluminum (Al) alloys have widespread applications. However, most Al inherently low mechanical strength. Nanotwins can induce high strength and ductility in metallic materials. Yet, introducing high-density growth twins into remains difficult due to its ultrahigh stacking-fault energy. In this study, it is shown that incorporating merely several atomic percent of Fe solutes enables the formation nanotwinned (nt) columnar grains with 9R phase Al(Fe) solid solutions. The nt Al-Fe...
Abstract Material performance in extreme radiation environments is central to the design of future nuclear reactors. Radiation induces significant damage form dislocation loops and voids irradiated materials, continuous often leads void growth subsequent swelling metals with low stacking fault energy. Here we show that by using situ heavy ion irradiation a transmission electron microscope, pre-introduced nanovoids nanotwinned Cu efficiently absorb radiation-induced defects accompanied...
Abstract The three-dimensional nature of twins, especially the atomic structures and motion mechanisms boundary lateral to shear direction twin, has never been characterized at level, because such is, in principle, crystallographically unobservable. We thus refer it here as dark side twin. Here, using high-resolution transmission electron microscopy atomistic simulations, we characterize "Equation missing" deformation twins magnesium. It is found that serrated comprised coherent twin...
In semi-coherent interface, a superposed network of interface dislocations accommodates the attendant coherency strains in adjacent crystals and their intersections (referred to as nodes) can act sinks sources for point defects because low formation energy. Nodes {111} interfaces are characterized with spiral pattern (SP), wherein line direction each dislocation entering node curves. The structure SP nodes is able switch between condensed expanded by either reaction or mechanical...
Topological crystalline insulators (TCIs) are a new class of topological materials that possess unique metallic surface states protected by mirror symmetry. Their properties expected to strongly depend on the orientation. By combining density functional theory (DFT) calculations and synthesis experiments, we demonstrate controlled growth single nanostructures prototypical TCI SnTe with distinct facets morphologies. Our suggest excess energy {111} surfaces can be either higher or lower than...
