英文摘要	Cu50Zr42Al8 amorphous alloy was prepared by copper mold casting process, then annealed at high temperature in a short time. Structural properties of the annealed bulk metallic glasses (BMGs) were analyzed by X-ray diffraction (XRD). Wear resistance was investigated by ball-on-disc reciprocating friction tester under dry sliding condition. The friction and wear behavior of Cu-based bulk metallic glasses and the influence of high-temperature treatments were studied. The results showed that CuZr2, ZrCu and AlCu2Zr phases were separated out after annealing at high-temperature for a short time, and the volume fraction of precipitated phase increased with the increase of annealing temperature. ZrCu phase decreased and new diffraction peaks of Al2Zr3 and AlZr3 phases appeared after annealing at 925. Friction and wear behavior improved greatly after annealing at 825 and 875, but decreased with the temperature continuing to increase. The sample annealed at 825 had the best friction behavior. The wear area, wear rate and the mean friction coefficient decreased to the minimum values: about 1.31×10-4 mm2, 0.011×10-4 mm3·N-1·m-1 and 0.11, respectively. The alloy treated at 925 had the worst friction coefficient, the wear area and wear rate outdistanced other samples: about 240.83×10-4 mm2 and 2.01×10-4 mm3·N-1·m-1, respectively. ©, 2014, Editorial Office of Chinese Journal of Rare Metals.
