Research Abstract

1) Glass-forming ability of Cu-Zr-Al-Ag alloys was significantly enhanced by the composition optimum. The Ta particles (40μm) homogenously distributed the Cu-Zr-Al-Ag bulk glassy alloys with diameters of 2-5mm were synthesized. The composites showed high strength and unusual plasticity. Ta particles seed the initiation of multiple shear bands and block the shear band propagation, leading to a net-like homogeneous distribution of the shear bands.
2) The large-size Zr-Cu-Al-Fe bulk glassy alloys containing nanocrystals with size of 5-10nm were obtained by copper mold casting. The composites exhibited a combination of high yield strength and large plasticity. The mechanism for the large plasticity of the new bulk glassy composites is elucidated.
