Abstract

The phase transition of Nb from body-centered cubic (bcc) to face-centered cubic (fcc) has been found in Cu/Nb nanostructured multilayers with modulation period (λ) spanning from 5 to 300. nm, and was analyzed by using a thermodynamic model. As λ decreases, the strength of multilayers increase and approach saturation of ∼2.88. GPa at a few nm layer thickness. Size dependent strengthening in present fcc/fcc Cu/Nb multilayers is explained in terms of dislocation based strengthening mechanisms. The enhanced modulus of fcc/fcc Cu/Nb is also observed.
