Characterizing heavy ions-irradiated Zr/Nb: Structure and mechanical properties

Abstrakt

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 (111) substrate by using magnetron sputtering and were subjected to heavy-ion irradiation at room temperature with different fluences.

Nanoindentation, XRD, DFT, SIMS, and Variable Energy Positron Annihilation Spectroscopy

(VEPAS) techniques were used to study the type and distribution of defects, and strain within the material as well as the changes in the hardness of the structures as a function of damage.
