| 英文摘要 | Metallic glasses (MGs) show significant potential for hypervelocity impact protection due to their high hardness and dynamic strength. In this study, the protective performance of a new Co33Os20Ta10B37 MG was systematically evaluated. Plate impact experiments revealed an ultra-high Hugoniot elastic limit (HEL) up to 19 GPa, setting a new record for metallic materials. Using the laser-induced micro-particle impact test (LIPIT), we characterized the impact response and protective performance of Co33Os20Ta10B37 subjected to SiO2 microparticle impact. The results demonstrated a high coefficient of restitution (COR) and dynamic strength for Co33Os20Ta10B37. More importantly, the low impact-mode ratio further indicates that it can efficiently withstand the high-velocity impact of micro-particles, as confirmed by the absence of craters in post-impact surface. These results emphasize the outstanding resistance of Co33Os20Ta10B37 MG to hypervelocity impact, underscoring its promising potential as an advanced protective material. |
