Abstract

The 30CrMnSiNi2A steel has been commonly used in the national defense industry and engineering areas. The fracture properties of the material are studied by dynamic tensile tests on a traditional Hopkinson system and three-point bend tests on a modified Hopkinson loading system. The dynamic tensile experiments results show that 30CrMnSiNi2A steel is sensitive of the strain rate. The dynamic fracture toughness of the material increases with the rise of loading rate, but its value is less than the static fracture toughness value. Move over, the fracture mechanism is investigated through macroscopic and microstructural analysis, which reveals that the fracture mechanism of 30CrMnSiNi2A belongs to quasi-cleavage fracture.
