Abstract

The dynamic compression testing of Mg₆₅O₂₀Ag₅Gd₁₀ bulk amorphous alloy was done by split Hopkinson pressure bar (SHPB) at the scope of strain rate of 10²-10³ s^-1. The fracture morphologies of Mg₆₅Cu₂₀Ag₅Gd₁₀ bulk amorphous alloy were studied by scanning electron microscopy. The results show that the most fracture strength value is 704 MPa of the Mg₆₅Cu₂₀Ag₅Gd₁₀ bulk amorphous alloy under dynamic compression and no macro-plastic phase during deformation process; the fracture strength of Mg₆₅Cu₂₀Ag₅Gd₁₀ bulk amorphous alloy has rise trend with a rise in the air pressure of shooting bullet, the fracture strain falls with a rise in compression load; the cleavage step exists on the fracture which proves the Mg₆₅Cu₂₀Ag₅Gd₁₀ bulk amorphous alloy to be brittle fracture, meanwhile the strip pattern and slip area are found on the fracture morphology.
