Abstract
Alloys of the copper-Cu5Zr eutectic have been directionally solidified over a range of growth rates. The tensile strength was found to be high, 0.6 to 1.0 GN m−2, in contrast to the poor electrical conductivity, typically 22 m Ω −1 mm−2. In order to improve the latter at the expense of the former, hypo-eutectic (copper-rich) alloys were also studied. Alloys of composition in the region of copper-4 wt % zirconium possessed a useful combination of properties but these were not superior to the properties of conventionally cast samples. These alloys were shown to be stable against exposure to elevated temperatures.
