The trade-off of strength and ductility of metals has long plagued materials scientists. To
resolve this issue, great efforts have been devoted over the past decades to develo** a …

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

Severe plastic deformation (SPD) techniques such as laser shock peening (LSP) have been
widely adopted to modify microstructure of materials. Understanding the plastic deformation …

Although many high-entropy alloys (HEAs) possess excellent mechanical properties, they
are not exempt from the common dilemma of strength–ductility trade-off in most cases, which …

Gradient nanostructure in aluminum alloy, constructed via a two-dimensional ultrasonic
surface burnishing process, displays enhanced tribocorrosion resistance in artificial …

Shear localization is an important failure mode, or even the dominant mode in metals at high-
strain rates. However, it is a great challenge to accurately predict the occurrence and …

Generally, strength and ductility are mutually exclusive in homogeneous metals.
Nanostructured metals can have much higher strength when compared to their coarse …
