英文摘要	Cu50Zr42Al8 amorphous alloy was prepared by copper mold casting process, then high-temperature treatment at different temperatures was carried out. Structural, thermal and compressive properties of the annealed BMGs were studied by X-ray diffraction (XRD), differential scanning calorimetry (DSC), scanning electron microscope (SEM) and compressive test methods. The results indicated: the sample treated at 873 K didn't form new phase, the other samples formed Cu10Zr7 and AlCu2Zr new phases, and with the treatment temperature increasing, the volume fraction of precipitated phase increased; the strength and plasticity of as-cast specimen was the best, and with the heat treatment temperature increasing, fracture strength firstly increased and then decreased. The sample treated at 1 148 K had the lowest fracture strength, the 1 123 K had the highest in the samples treated. In addition to the as-cast specimen, only the sample treated at 1 198 K showed plasticity with the plastic strain 0.83%.
