Abstract

In niobium filaments of the Cu-7.7%Nb composite under cold-drawing beginning from the true strain of 8.5, macrostrains are observed according to the X-ray data, which is confirmed by TEM data, which demonstrate distortions of niobium lattice and formation of partially coherent boundaries (110)Nb || (111)Cu. These macrostrains are anisotropic and higher than those in the Cu-18%Nb composites.High-strength Cu-Nb composites with high electrical conductivity were developed to protect magnetic systems from destruction under the action of Lorentz forces, but the possibilities of their application are much wider. Unique in situ composites of small diameter based on copper with a reduced niobium content of 7.7 wt.% are investigated to contribute to the development of more cost-effective high-strength composite conductors. In this work, the change of tense state in the components of the Cu-7.7 % Nb composite under cold-drawing from the true strain of 8.5 to 11.2 has been determined by X-ray diffraction analysis and transmission electron microscopy. It has been found that in niobium filaments beginning from the true strain η = 8.5, macrostrains are observed according to the X-ray data, which is confirmed by TEM data, which demonstrate distortions of niobium lattice and formation of partially coherent boundaries (110)Nb || (111)Cu. These macrostrains are anisotropic and higher than those in the Cu-18 % Nb composites. The microstrains have also been detected in niobium, which increase with increasing true strain of the Cu-7.7 % Nb composite. The results obtained will help to further determine the contribution of the Cu / Nb interfaces to the anomalous strength of this class of composite materials.
