Severe plastic deformation (SPD) is effective in producing bulk ultrafine-grained and
nanostructured materials with large densities of lattice defects. This field, also known as …

The evolution of the new microstructures produced by two types of dynamic recrystallization
is reviewed, including those brought about by severe plastic deformation (SPD). The …

Mechanically strong and ductile load–carrying materials are needed in all sectors, from
transportation to lightweight design to safe infrastructure. Yet, a grand challenge is to unify …

Many traditional approaches for strengthening steels typically come at the expense of useful
ductility, a dilemma known as strength–ductility trade-off. New metallurgical processing …

Architected materials that consist of periodic arrangements of nodes and struts are
lightweight and can exhibit combinations of properties (such as negative Poisson ratios) that …

Develo** ultrahigh-strength steels that are ductile, fracture resistant, and cost effective
would be attractive for a variety of structural applications. We show that improved fracture …

A dual-heterogeneous structure with bimodal grain size distributions of both austenite and
B2 phase was developed in a novel ultralight steel by a simple rolling and annealing …

Refractory tungsten (W) is notoriously brittle at room temperature, which restricts its
workability and narrows the temperature range of critical applications. Here, we report a …

Steels with medium manganese (Mn) content (3∼ 12 wt-%) have emerged as a new alloy
class and received considerable attention during the last decade. The microstructure and …

Fatigue failures create enormous risks for all engineered structures, as well as for human
lives, motivating large safety factors in design and, thus, inefficient use of resources. Inspired …
