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 …

Strengthening materials traditionally involves the controlled creation of internal defects and
boundaries so as to obstruct dislocation motion. Such strategies invariably compromise …

Grain refinement into the nanoscale greatly hardens metals and alloys but reduces the
stability. By means of cryogenic plastic deformation at very high strain rates, a high …

Nearly 90 per cent of service failures of metallic components and structures are caused by
fatigue at cyclic stress amplitudes much lower than the tensile strength of the materials …

This article reviews recent basic research on two classes of twins: growth twins and
deformation twins. We focus primarily on studies that aim to understand, via experiments …

The mechanical behavior of nanolaminates is dominated by interfaces that act as sources,
barriers, and preferred sites for storage and dynamic recovery of glide dislocations. In this …

Using in situ transmission electron microscopy, we studied the stability of growth twins. We
observed the rapid migration of incoherent twin boundaries (ITBs), indicating that nanotwins …

Anisotropic plastic deformation in columnar-grained copper in which preferentially oriented
nanoscale twins are embedded is studied by experimental testing, crystal plasticity modeling …

Coherent twin boundaries (CTBs) are widely described, both theoretically and
experimentally, as perfect interfaces that play a significant role in a variety of materials …

CrN-coated Zircaloy samples were prepared by cathodic arc ion plating, and the
microstructure, stability, and oxidation behaviors of the CrN coatings in high-temperature …
