Abstract

For the first time, the electrical resistivity of molten Cu64.5Zr35.5, Cu50Zr50, and Cu33.3Zr66.7 alloys at temperatures up to 1600 K has been measured by the contactless method in a rotating magnetic field. The measurements were taken during cooling in a helium atmosphere with a purity of 99.995%. The error of the electrical resistivity determination did not exceed 5%. It has been found that the electrical resistivity of liquid Cu64.5Zr35.5, Cu50Zr50, and Cu33.3Zr66.7 alloys decreases linearly with increasing temperature, while it increases with temperature for liquid copper and zirconium. The concentration dependences of the electrical resistivity and its temperature coefficient have a maximum at 55 at % and a minimum at about 60 at % Zr, respectively. These concentration dependences are similar to the dependences obtained for amorphous alloys and are explained in the framework of the Ziman theory.
