Experiments of X-ray diffraction for liquid Cu70Ni30 alloy above and below its liquidus (1 230℃) have been carried out. By the analysis of experimental results, it is discovered that difference between structures of liquid and undercooled Cu70Ni30 alloy is their cluster sizes. The correlation radius of cluster is 1.125 nm and the atom number of cluster is 403 at 1 250_1 400℃, and they are 1.3 nm and 704 respectively at the undercooled liquid state (1 200℃). The structure of liquid Cu70Ni30 alloy is fcc short order and its solid structure, fcc, is kept from liquid fcc short order.
