Abstract

Zr_50.5Cu_36.5Ni₄Al₉ bulk amorphous alloy has been prepared by copper mold casting method. The dynamic compression characteristics and the features of fracture morphology of Zr_50.5Cu_36.5Ni₄Al₉ bulk amorphous alloy at room temperature(25°C) and cryogenic temperature(-40°C) were investigated with split Hopkinson pressure bar (SHPB) and S-4800 scanning electronic microscope (SEM). The results show that, under the dynamic compression load, the anti-compressive strength decreased with the load increase of Zr_50.5Cu_36.5Ni₄Al₉ bulk amorphous alloy. The dynamic anti-compressive strength of Zr_50.5Cu_36.5Ni₄Al₉ bulk amorphous alloy has cryogenic temperature sensitivity at -40°C temperature. The main fracture morphology of the Zr_50.5Cu_36.5Ni₄Al₉ bulk amorphous alloy shows the vein patterns with the crack and amorphous alloys melted at room temperature. The main fracture morphology of the Zr_50.5Cu_36.5Ni₄Al₉ bulk amorphous alloy shows the herringbone pattern at -40°C temperatures.
