Materials subjected to high dose irradiation by energetic particles often experience severe
damage in the form of drastic increase of defect density, and significant degradation of their …

The recent studies on nanotwinned (NT) and hierarchical nanotwinned (HNT) face-centered
cubic (FCC) metals are presented in this review. The HNT structures have been supposed …

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 …

Strengthening of metals through nanoscale grain boundaries and coherent twin boundaries
is manifested by a maximum strength—a phenomenon known as Hall–Petch breakdown …

The breakdown from grain-size strengthening to softening mechanisms is generally well
understood for high-purity nanocrystalline materials when the mean grain size decreases to …

The greatly increased grain boundary (GB) mobility in nanograined metals under
mechanical loading is distinguished from that in their coarse-grained counterparts. The …

Twins are domain crystals inside their parent crystals, where they share some of the same
crystal lattice points in a symmetrical manner. The formation and growth of twins result in …

Gradient materials often have attractive mechanical properties that outperform uniform
microstructure counterparts. It remains a difficult task to investigate and compare the …

In recent years, nanotwinned (NT) materials have attracted great attention in several
research areas because of many advantageous properties (eg, high conductivity, excellent …

A leaf-inspired nanoengineering is employed for the structural design of carbon nanofillers.
We fabricate leaf-like carbon nanotube (CNT)-graphene nanoribbon (GNR) hybrids as novel …
