Abstract Bulk nanostructured (ns)/ultrafine-grained (UFG) metallic materials possess very
high strength, making them attractive for high strength, lightweight and energy efficient …

A large number of polycrystalline materials, both manmade and natural, display preferred
orientation of crystallites. Such alignment has a profound effect on anisotropy of physical …

Two of the key parameters that are useful for understanding the deformation kinetics in
metals with ultrafine grain (UFG) and/or nanocrystalline (nc) microstructure are the strain …

Dislocation motion in body centered cubic (bcc) metals displays a number of specific
features that result in a strong temperature dependence of the flow stress, and in shear …

The mechanical behaviors of consolidated iron with average grain sizes from tens of
nanometers to tens of microns have been systematically studied under uniaxial compression …

In the past twenty years, new experimental approaches, improved models and progress in
simulation techniques have brought new insights into longstanding issues concerning …

The newly-surged high-entropy alloys (HEAs), in particular the refractory HEAs, manifest
excellent properties for practice applications. In this work, we systematically investigated the …

The low-temperature plastic yield of α-Fe single crystals is known to display a strong
temperature dependence and to be controlled by the thermally activated motion of screw …

The softening effect in metals due to ultrasonic vibration is used in many industrial
applications. The existing understanding of such an acoustoplastic effect is one in which the …

Peach–Koehler theory is implemented to simulate the motion of arbitrarily configured
interacting dislocations, located on arbitrary glide planes and having any allowed Burgers …
