There has been a long-standing controversy on how dislocations interact with interfaces. Here we report in-situ observations that in Cu–brass heterostructured TEM film Frank–Read sources are the primary dislocation sources. They were dynamically formed and deactivated throughout deformation grain interior, which never reported before. This observation indicates strain gradient near interfaces cannot be quantitatively related to density of geometrically necessary dislocations, it was...
An ideal ultrafine-grained (UFG) microstructure for high strength and ductility should have short dislocation-slip path to impede dislocation slip very low density ensure more room accumulation. Such a is hard produce, especially UFG metals produced by severe plastic deformation techniques. Here, we report an structure reverse transformation of deformation-induced martensite in 304 L austenitic stainless steel. It small grains nanotwins both ductility. This approach applicable face-centered...
Here we advocate the strategic design of dispersed heterostructure to retain ductility and toughness in high-strength metals, using equiatomic CrCoNi alloy as an example. Dispersed heterostructure, with nanograins and/or ultrafine grains (the hard zone) around micrometer-sized grain soft zone), is fabricated by cold-rolling followed sequential flash-annealing at increasing temperatures. It displays a decent uniform elongation ∼ 20 % exceptional strain energy density limit up 240 mJ/mm3...
The hetero-zone boundary affected region (HBAR), with a high strain gradient, plays crucial role in the synergistic deformation of layered materials. Our previous experimental study demonstrated that decreasing interfacial spacing leads to higher fraction HBAR and an enhanced combination strength ductility. In this work, conventional mechanism-based gradient (CMSG) plasticity model is adopted simulate tensile behavior Cu–Fe materials three different spacings. simulation results indicated...
