Nowadays, advanced aluminum matrix composites (AAMCs) are known as the dominant
emerging materials employable in different industrial sectors. The reason behind the use of …

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

Heterostructured metals possess superior mechanical properties exceeding the prediction
by the rule-of-mixtures. However, it remains a challenge to understand the key …

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

A strength-ductility trade-off usually occurs when grains are refined to increase strength. A
question arises on if there exists a grain size for the best strength-ductility combination, ie …

The interfaces introduced in metals by heterostructural design play crucial roles in
mechanical behaviors. Here the effect of gradient interfaces on mechanical behavior was …

A single-phase bimodal grain structure is considered to develop a physical model to quantify
hetero-deformation induced (HDI) strengthening at the yield point, which cannot be simply …

Deformation mechanism-based constitutive modeling can serve as a flexible tool to optimize
the microstructure of hetero-structured metals for achieving better mechanical performance …

Hetero-deformation induced (HDI) hardening has been attributed to geometrically necessary
dislocations (GNDs) that are needed to accommodate strain gradient near the interfaces of …

Tailoring heterogeneities could bring out excellent strength-ductility synergy properties. A
gradient nano-grained (GNG) structure, ie grain size range from nanometer (∼ 50 nm) at …
