“…Figure 1 shows the conductivity of the in situ Cu-XFe (X = 11, 14, 17) microcomposites with different cold deformation strains produced using the thermomechanical procedure II. The conductivity of these in situ microcomposite decreased with increasing iron content and also with increasing cold deformation strain from g = 7 to g = 7.8, which was similar to the previous research results ( Ref 7,21,26). However, the conductivity of the microcomposite increased with increasing cold deformation strain from g = 4 to g = 7.…”

This paper studied the electrical resistivity of in situ Cu-Fe microcomposites using theoretical analysis and experiments. The model alloys Cu-XFe (X = 3, 4.3, 11, 14 and 17 wt.%) were produced by casting, and the microcomposites were prepared by thermomechanical treatment. The solid solubility of iron in the copper matrix was measured using an energy dispersive spectrometer. The electrical resistivity and conductivity was evaluated using a micro-ohmmeter. The conductivity of the Cu-XFe (X = 3 and 4.3) was essentially constant at $ 40% IACS. The conductivity of the Cu-XFe (X = 11, 14, 17) microcomposites decreased in a nonlinear manner with increasing iron content and increasing cold deformation strain, which was mainly determined by the interface scattering resistivity caused by the interface between the copper matrix and the iron fibers.

The US national high magnetic field laboratory builds and uses various high field magnets for fundamental research. In building high field magnets, a variety of high strength composites are required because of the Lorentz stresses generated by high field exceeding the strength of most of the materials, particular conductors. For example, a field of 60 T can generate a magnetic pressure that corresponds to a stress in the conductor of 1.5 GPa, which is at the limit of known conducting materials with conductivity higher than 70% International Annealed Copper Standard and sizes suitable for building high field magnets. The design of high field magnets is limited by these forces and, consequently, by the available materials. At the same time, the materials need to have excellent physical properties. For instance, the conductors need to have high electrical conductivity and high specific heat and the superconductors should have high critical current in field and low alternative current losses. This paper outlines our requirements and research on metal matrix composite materials for building high field magnets. The discussions include both the macrocomposite and microcomposite. The scales of the structures in the composites are from millimeters to nanometers.
