Gradient grained metals whose microstructure is characterized by a spatially graded grain
size distribution show a better strength-ductility combination than their homogeneous …

Gradient nano-grained (GNG) metals are a unique class of materials with spatial gradients
in grain size, typically from the surface to the bulk. Here the gradient mechanical behavior in …

Gradient nano-grained (GNG) metals have shown a better strength-ductility combination
compared to their homogeneous counterparts. In this paper, the mechanical properties and …

Overcoming the trade-off between strength and ductility in metallic materials is a grand
challenge. Recently, materials with a gradient nano-grained (GNG) surface layer adhering to …

Gradient nano-grained (GNG) materials have shown synergetic high strength and ductility
due to their unique gradient microstructure, where the grain size changes from tens of …

The geometrically non-linear scale dependent response of polycrystal FCC metals is
modelled by an enhanced crystal plasticity framework based on the evolution of several …

Gradient nano-grained (GNG) materials, inside which grain size increases gradually from
nano-scale in the surface to micro-scale in the substrate, have shown synergetic strength …

A strain gradient-dependent crystal plasticity approach is presented to model the constitutive
behaviour of polycrystal FCC metals under large plastic deformation. In order to be capable …

Gradient structured (GS) materials are ubiquitous in biological systems and now
increasingly adopted in engineering systems to achieve desirable combinations of …

In this paper, it is shown that the occurrence of dislocation pileups across grain boundaries,
as well as subsequent emission to the adjacent grains, is captured theoretically by gradient …
