Evaluation of plastic deformation ability of Cu/Ni/W metallic multilayers
نویسندگان
چکیده
Plastic deformation behavior of Cu/Ni/W metallic multilayers with individual layer thickness ranging from 5 nm to 300 nm is investigated by nanoindentation testing. The experimental results reveal that the composite still exhibits indentation-induced plastic deformation instability and the loss of strain hardening ability at the nanometer scale even if the composite contains two kinds of layer interfaces (face centered cubic(FCC)/FCC and FCC/body centered cubic) simultaneously. Plastic deformation behavior of the nanolayered material was evaluated and analyzed.

Ni-Co/Cu multilayers have been grown by electrodeposition method from a single electrolyte (based on Ni(SO4).6H2O, Co(SO4).7H2O, Cu(SO4) and H3BO3) using galvanostatic control on titanium sublayers. The X-ray diffraction (XRD) patterns confirmed the multilayered structure with the nanometer thicknesses. Also, electron diffraction x-ray (EDX) analysis confirmed the purity of deposited samples. ...

In this work electrodeposited Ni-Cu/Cu metallic multilayered films with different thicknesses of Ni and Cu were prepared on (100) polycrystalline Cu substrates. The nanostructure of the multilayers was studied using XRD. The existence of satellite peaks in the XRD patterns showed that the multilayered films have superlattice structures. The difference between the intensity of ML(200) and ML(11...

We synthesized CuZr/Cu multilayers and performed nanoindentation testing to explore the dependence of plastic deformation modes on the thickness of CuZr layers. The Cu layers were 18 nm thick and the CuZr layers varied in thickness from 4 nm to 100 nm. We observed continuous plastic co-deformation in the 4 nm and 10 nm CuZr - 18 nm Cu multilayers and plastic-induced shear instability in thick C...
