| Abstract: | For their excellent mechanical, physical and chemic performance, bulk metallic glasses and their composite materials is now becoming an active research focus. Especially, metallic glass matrix composite may be employed as the material of kinetic enrgy penetrator for its intensive shear banding sensitivity. The present paper presents advances in the research on compressive shear deformation and fracture characteristics and self-sharpening behavior during the high-speed impact of bulk metallic glasses and the... |
