The thermal decomposition behavior, the microstructural evolution and its influence on the mechanical properties of a supersaturated Cu-Co solid solution with ~100 nm average grain size prepared by severe plastic deformation is investigated under non-isothermal and isothermal annealing conditions. Pure fine-grained Cu and Co exhibit substantial grain growth upon annealing, whereas the Cu-Co alloy is thermally stable at the same annealing temperatures. The annealed microstructures are studied by independent characterization methods, including scanning electron microscopy, electron energy loss spectroscopy and atom probe tomography. The phase separation process in the Cu-Co alloy proceeds by the same mechanism, but on different length scales: a fine scaled spinodal-type decomposition is observed in the grain interior, simultaneously Co and Cu regions with a larger scale are formed near the grain boundary regions. Subsequent grain growth at higher annealing temperatures results in a microstructure consisting of the pure equilibrium phases. Such mechanisms can be used to tailor nano structures to optimize certain properties. Published in

“…In order to improve the strength of copper alloys, composition design and preparation technology have been widely studied [1][2][3][4] . The high strength of copper alloys has been reported to be 900 to 1,500 MPa for Cu-Be base alloys after an optimum age-hardening treatment; 600 to 1,500 MPa for Cu-M (M=Nb or Ag) alloy wires and 1,350 to 1,800 MPa for Cu-Zr alloy wires produced by the heavy cold drawing method [5][6][7][8] . To obtain the high strength performance of copper alloys, complicated subsequent manufacturing processes were needed after casting.…”

“…Furthermore, drawn Cu-Ag alloy wires 10,11) with a eutectic lamellar structure created by casting have also been studied. Sakai et al studied Cu-Ag alloys reinforced by ber-like structures in which the primary and eutectic phases underwent elongation during a cold wire-drawing process [12][13][14] . In contrast, other efforts have focused on the production of lean Cu alloy materials with high electrical conductivity 15,16) .…”

This study applied a vertically upwards continuous casting (VUCC) mass-production method to the pilot-scale production of hypoeutectic Cu-xZr (x = 0.25-5 at%) alloy rods. The microstructures of these VUCC rods were investigated and compared with those of rods produced by copper mold casting (CMC). In addition, the wire-drawing ability of the VUCC rods was examined, and the adaptability of the VUCC method to the mass production of hypoeutectic Cu-Zr alloys was fully investigated. The results show that VUCC provides a higher rate of cooling than CMC, with the resulting dendritic microstructure expected to contribute to its arm-spacing re nement. Furthermore, the VUCC rods exhibit good wire-drawing ability. The ultimate tensile strength, total strain to fracture, and electrical conductivity of Cu-2.5Zr (at%) alloy wires with diameter of 13.8 μm drawn from a VUCC rod are 1882 ± 28 MPa, 2.2 ± 0.2%, and 21% IACS (i.e. 21% of the International Annealed Copper Standard conductivity of annealed copper), respectively. The results suggest that VUCC has good potential to be adapted for mass production of hypoeutectic Cu-Zr alloy rods.
