Intermetallic compounds because of their high melting point temperature, good mechanical properties, and high corrosion resistance are attractive. The Zr2Cu intermetallic compound can be produced by a mechanical alloying method. In this study, alloying was carried out by using the pure copper and zirconium powders under argon atmosphere at different time durations from 30 to 120 minutes. Milling speed was chosen as 220, 250, and 280 rpm. Mechanical alloying was done with five different balls to powder ratios (BPR) of 1:10, 1:15, 1:20, 1:25, 1:50. Prepared powders were studied by X-Ray Diffraction (XRD). XRD results showed that with increasing milling time and ball to powder ratio, the amount of amorphous phase increases, however, particle size reduces. By increasing the ball to powder ratio, speed and time of milling crystallite size decreases, but lattice strain increases.
