Nanocrystalline (nc) materials can be defined as solids with grain sizes in the range of 1–
100 nm. Contrary to coarse-grained metals, which become more difficult to twin with …

Strengthening materials traditionally involves the controlled creation of internal defects and
boundaries so as to obstruct dislocation motion. Such strategies invariably compromise …

The strength of nanocrystalline and nanotwinned metals stops increasing or even starts
decreasing when their grain size or twin thickness is below a critical size—a phenomenon …

The strength of polycrystalline materials increases with decreasing grain size. Below a
critical size, smaller grains might lead to softening, as suggested by atomistic simulations …

Abstract Carbon nanotubes (CNTs) reinforced Al matrix composites containing high-density
stacking faults were successfully fabricated through spark plasma sintering (SPS) and …

By means of dynamic plastic deformation (DPD) with high strain rates, a bulk nanostructured
316L austenitic stainless steel consisting of nano-sized grains embedded with bundles of …

We have investigated the rate sensitivity of flow stress and the extent of strengthening in
polycrystalline copper containing different volume fractions of nano-sized twins, but having …

Anisotropic plastic deformation in columnar-grained copper in which preferentially oriented
nanoscale twins are embedded is studied by experimental testing, crystal plasticity modeling …

An electro-deposited Cu sample with a high density of nano-scale growth twins shows an
ultrahigh tensile strength (∼ 1GPa) with a considerable plastic strain (> 13%). Both the …
