Abstract
The Split Hopkinson Pressure Bar(SHPB) was used for investigating dynamic mechanical properties of extrusion formed AZ61 alloy. The samples after impact were analized by scanning elec-tron microscope (SEM) and metallography. The alloy's dynamic crack performance and plastic de-formation mechanism at room temperature were discussed. The results showed that the alloy per-formed strain hardening under high strain rate compression. The samples were brittle ruptured under impact basically, but a few dimples can also be found on the fracture section. Twinning and glide co-acted during the alloy's plastic deformation. Remehing was observed under SEM while the strain rate of the test reached 2.3 × 10~3.关键词
