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 …

Nanostructured materials contain an extremely high density of interfaces. The properties of
these materials when exposed to extreme conditions of radiation dose, stress, deformation …

A grand challenge in material science is to understand the correlation between intrinsic
properties and defect dynamics. Radiation tolerant materials are in great demand for safe …

Nanoscale metallic multilayers have been shown to have a wide range of outstanding
properties, which differ to a great extent from those observed in monolithic films. Their …

In this work, the radiation responses of Zr/Nb nanostructured metallic multilayers (NMMs) are
studied. The nanostructures with different layer thicknesses were deposited on Si (1 1 1) …

Sputter-deposited Cu/V nanolayer films with individual layer thickness, h, varying from 1 to
200nm were subjected to helium (He) ion irradiation at room temperature. At a peak dose …

Helium (He) bubbles are typical radiation defects in structural materials in nuclear reactors
after high dose energetic particle irradiation. In the past decades, extensive studies have …

Heterostructured materials comprised of relatively soft/hard disparate phases typically
exhibit composite strengthening but lack plastic deformability at ambient temperatures …

Interfaces are good traps for implanted He, but are also susceptible to He-induced
embrittlement. Better understanding of the mechanisms of He interactions with interfaces …

Helium (He) exerts a significant influence on the mechanical behavior of irradiated
materials. The microstructural evolutions and hardening mechanisms of pure 1μm thick Cu …
