Specific Features of Interfaces in Cu-Nb Nanocomposites

Abstract:

The structure and properties of multi-rod Cu-Nb composites with the true strain of 10.2 and 12.5 have been studied by TEM, SEM and microhardness measurements. The non-uniform distribution of Nb ribbons throughout the composite cross sections was revealed, at higher strain their structure being more dispersed. In both wires the Cu/Nb interfaces are partly coherent, and the Nb lattice is more distorted at interfaces than in the bulk. The behavior at heating was studied in the temperature range of 300-800^оС. In the range of 600-800^oC complete coagulation of Nb filaments accompanied with drastic microhardness drop is observed. The thermal stability of Cu-Nb nanocomposites is higher than that of Nb and Cu nanostructured by SPD.
