TLDR
In this article, the authors present an approach for processing bulk nanocomposites containing interfaces that are stable under irradiation, which is the key factor in reducing the damage and imparting stability in certain nanomaterials under conditions where bulk materials exhibit void swelling and/or embrittlement.About:

Mechanism of Radiation Damage Reduction in Equiatomic Multicomponent Single Phase Alloys
F. Granberg,Kai Nordlund,Mohammad W. Ullah,Ke Jin,Chenyang Lu,Hongbin Bei,Lumin Wang,Flyura Djurabekova,William J. Weber,Yanwen Zhang +9 more
TL;DR: A combination of experimental and modeling efforts reveals a substantial reduction of damage accumulation under prolonged irradiation in single-phase NiFe and NiCoCr alloys compared to elemental Ni, explained by reduced dislocation mobility, which leads to slower growth of large dislocation structures.

TL;DR: In this article, the authors consider the extensive experimental and computer simulation studies that have been performed over the past several decades on what the nature of the primary damage is, and provide alternatives to the current international standard for quantifying this energetic particle damage, the Norgett-Robinson-Torrens displacements per atom (NRT-dpa) model for metals.

Growth Twins and Deformation Twins in Metals
TL;DR: In this article, a review of recent basic research on two classes of twins: growth twins and deformation twins is presented, focusing primarily on studies that aim to understand, via experiments, modeling, or both, the causes and effects of twinning at a fundamental level.

Principles of equal-channel angular pressing as a processing tool for grain refinement
TL;DR: In this article, a review examines recent developments related to the use of ECAP for grain refinement including modifying conventional ECAP to increase the process efficiency and techniques for up-scaling the procedure and for the processing of hard-to-deform materials.

Materials Challenges in Nuclear Energy
Steven J. Zinkle,Gary S. Was +1 more
TL;DR: In this article, the three major materials challenges for the current and next generation of water-cooled fission reactors are centered on two structural materials aging degradation issues (corrosion and stress corrosion cracking of structural materials and neutron-induced embrittlement of reactor pressure vessels), along with improved fuel system reliability and accident tolerance issues.

Paradox of strength and ductility in metals processed by severe plastic deformation
TL;DR: In this paper, a combination of high strength and high ductility produced in metals subject to severe plastic deformation (SPD) was shown to enable deformation by newmechanisms.

Efficient annealing of radiation damage near grain boundaries via interstitial emission.
TL;DR: Simulations show that grain boundaries in copper can act as sinks for radiation-induced defects, and find thatgrain boundaries have a surprising “loading-unloading” effect.
