The microcompression method was used to investigate the compressive plastic flow behavior of nanolayered crystalline/amorphous (C/A) Cu/Cu–Zr micropillars within wide ranges of intrinsic layer thicknesses (h ∼ 5–150 nm) and extrinsic sample siz

By using microcompression methodology, deformation of nanolayered Cu/Zr micropillars was systematically investigated within wide ranges of intrinsic layer thickness (5–100 nm) and extrinsic sample size (300–1200 nm). The intrinsic size effect, ex

Length-scale dependent hardness ( H ) and indentation modulus ( E ) are systematically investigated in nanostructured Cu/Cr multilayer films with a wide modulation period ( λ ) range from 5 nm to 250 nm. H is gradually increased with reducing λ dow

The strain hardening behavior of nanolayered Cu/Zr micropillars was studied using the microcompression technique, which revealed that both the strain hardening exponent and the strain hardening rate are controlled by the intrinsic rather than extrins

Hardness, activation volume and strain-rate sensitivity of Cu/Cr (face-centered cubic (fcc)/body-centered cubic) and Cu/Zr (fcc/hexagonal close-packed) nanostructured multilayer films have been systematically measured as a function of modulation peri

The mechanical behavior of incoherent Cu/Zr multilayers was studied in uniaxial compression experiments using micropillars with individual layer thicknesses (h) ranging from 5 to 100 nm. The deformation behavior of these micropillars are size depende

The plastic deformation and fracture behavior of two different types of Cu/ X ( X = Nb, Zr) nanostructured multilayered films (NMFs) were systematically investigated over wide ranges of modulation period ( λ ) and modulation ratio ( η , the ratio o
