Název v původním jazyce

Length-scale-dependent mechanical behaviour of Zr/Nb multilayers as a function of individual layer thickness

Popis výsledku v původním jazyce

Nanostructured metallic multilayers systems continue to garner interest because of their promising mechanical properties, exploitable in the field of materials engineering. These novel materials show high yield strengths, anomalous Young's modulus valuesand even superior radiation tolerance for layer thicknesses up to a few tens of nanometers. However, there are still many unknowns related to the deformation mechanisms operating at the nanoscale because of deformation mechanisms, in this nanoscale, depend directly on the layer thickness and the combination of different or similar crystal structures in the interface. The objective of this work is to produce Zr/Nb multilayers and investigate the dependence of deformation mechanisms when the layer thickness is reduced. Nanoindentation hardness as a function of periodicity, lambda, has been measured for Zr/Nb multilayers. It has been found that for decreasing h the yield strength values, sigma(2.7), do not increase. For lambda=60 nm and l
