In polycrystalline metals, plastic deformation is accompanied by lattice rotations resulting from dislocation glide. Following these in three dimensions requires nondestructive methods that so far have been limited to grain sizes at the micrometer scale. We tracked of individual grains nanograined nickel using three-dimensional orientation mapping a transmission electron microscope before and after situ nanomechanical testing. Many larger-size underwent unexpected rotations, which we...
Abstract AZ31 Mg alloy was processed by accumulative roll-bonding (ARB) and hot rolling (HR), respectively, followed annealing. Layered bimodal structures characterized an alternative distribution of fine-grained layers coarse-grained were obtained in the ARB samples, while mixed achieved HR samples. The samples have superior combinations high strength good elongation compared to indicating a clear effect layered on mechanical properties alloy. is related grain size; ductility attributed...
The use of single-crystal substrates as templates for the epitaxial growth overlayers has been a primary principle materials epitaxy more than 70 years. Here we report our finding that, though counterintuitive, 2D can be epitaxially grown on twinned crystals. By establishing geometric to describe alignment high-index surfaces, show that material islands two sides twin boundary well aligned. To validate this prediction, wafer-scale Cu foils with abundant boundaries were synthesized, and...
Abstract Strength and ductility are mutually exclusive if they manifested as consequence of the coupling between strengthening toughening mechanisms. One notable example is dislocation in metals, which invariably leads to reduced ductility. However, this trend averted metastable austenitic steels. A one-step thermal mechanical treatment (TMT), i.e. hot rolling, can effectively enhance yielding strength steel from 322 ± 18 MPa 675 15 MPa, while retaining both formability hardenability. It...
With focus on annealing twins, the microstructural evolution of cold rolled high purity aluminium was characterized in-situ during using electron backscatter diffraction technique. It found that twins developed recrystallization. Many but not all were gradually removed grain growth. The boundary energies boundaries in a network associated with are estimated and reasons why most disappear while few remain discussed.
Understanding the coarsening mechanisms and role of solute atoms during recovery annealing ultrafine lamellar-structured alloys produced by high strain deformation is crucial to tailor their microstructures mechanical properties. In present work, a Al–0.3%Cu alloy with boundary spacing 200 nm was prepared cold rolling von Mises 4.5 (a thickness reduction 98%), featuring Cu segregation angle lamellar boundaries. During in temperature range 100–175 °C, precipitation fine Al2Cu particles...
