“…Except for Al/CNT composites, the atomistic study based on MD simulation was conducted to explore the effect of CNTs on low-energy He ion irradiation endurance in CNT/Fe composites. [134] It was demonstrated that the He atoms tended to aggregate at the CNTs outer surface under the irradiation energy of 300 eV. And CNTs postponed the formation of He bubbles.…”

Interfaces including grain boundaries and heterophase interfaces could withstand the radiation damage via providing sites for trapping the defects. With the urgent demand for high radiation-tolerance nanostructured materials, exploration of the structural properties, especially the role of the interfaces on the radiation response in the nanomaterials, is of significant essentialness in developing the design of new radiation-resistant materials. Herein, the recent progress and development of two main kinds of interfaces, namely the grain boundaries in nanocrystalline and the hetero-phase interfaces in nanolayered materials and nano-composites, in nanostructured materials that are designed for radiation tolerance are summarized. In addition, the radiation response and resistant mechanism under irradiation conditions of the nanocrystalline materials like metals, single-phase alloys, and ceramics, as well as the nanocomposites like nanolayered metals, nanolayered ceramics, metal-carbon nanocomposite, and nanoparticle dispersed steels, are reviewed. Finally, challenges and perspectives are proposed to offer advice for the development of radiation resistance nanomaterials.

“…Extensive efforts have been made in the study of the CNT-reinforced metallic nanocomposites, both theoretically and experimentally [18][19][20][21]. Aluminum is the most popular metal-matrix due to its availability, low cost, and reasonably good mechanical characteristics [22][23][24][25][26][27]. Copper is an excellent metal with outstanding thermal conductivities, electric conductivities, corrosion resistance, and many other merits, resulted in broad applications in industrial machinery and electrical devices [28][29][30].…”

Carbon nanotubes are outstanding reinforcements owing to their unparallel strength, while their effects on the copper nanowire are still not fully understood, hampering their broad applications. Herein, we have investigated the tensile behaviors of the nanocomposite-wire of carbon nanotube-copper using molecular dynamic simulations. For the nanocomposite, both the coated and embedded carbon nanotubes increase the Young's modulus, fracture stress and toughness of the copper nanowire. A reinforcement of over fivefold in both yield strength (5.3 times) and toughness (5.1 times) has been achieved when the carbon nanotubes are coated on the copper nanowires, as well as 1.7 times in the Young's modulus. Higher temperatures and lower loading rates reduce the reinforcement.
