A strategy for improving mechanical properties of metallic glass by tailoring interface structure
Source abstract
Abstract
Abstract The strength-plasticity trade-off of the metallic glass (MG) is a topical issue that researchers are constantly pursuing. Controlling the glass/glass interface (GGI) structure has become a key avenue for advancing MG performance. Here, the effect of the Cu composition in the boundary region (BR) (i.e., GGI structure) on the mechanical properties of the Cu85Zr15/CuxZr100-x dual-phase nanoglass (DPNG) under tensile loading is investigated by molecular dynamics simulation method. The results indicate that the strength of the DPNG can be significantly improved while its excellent plasticity is maintained by adjusting the Cu composition in the BR. The results also show that the mechanical properties of the DPNGs are not only related to the strength of the BR and the grain region (GR), but also to the GGI structure. The optimal matching relationship between the GR and the BR is obtained. The results will present a theoretical basis for developing the high-performance DPNG.
