| 英文摘要 | To investigate the 'structure-property' correlation in the high-entropy bulk metallic glass composites (HEBMGCs), a series of in-situ dendrites-reinforced Zr28Ti19Hf19Nb9.5Co5.5Be19 HE-BMGCs containing different microstructures are fabricated by varying the cooling rate (R). The underlying correlation between microstructure characteristics of dendrites and tensile properties of HE-BMGCs are elucidated by the postmortem microstructure observation and fracture analysis. The critical investigation shows the volume fraction (Vd), size (a) and arm diameter (d) of dendrite increase with decreasing R, whereas the interdendritic spacing (& ANGS;) decreases correspondingly. The larger d is more beneficial to enhance the back-stress-induced hardening effect of HE-BMGCs, while the strengths of all the HE-BMGCs are negative linear correlation with their Vd (56-70%). Besides, the finer a matches the size of 'plastic zone' associated with larger & ANGS;, which results in higher tensile ductility (-6.4%). Therefore, the combination of finer a and appropriate Vd at higher R is favorable for HE-BMGCs to obtain better ductility and higher strength. Our findings provide an important implication for the microstructural optimization of HE-BMGCs with desirable mechanical properties. |
