摘要：A series of Ti-Zr-Be-Fe bulk metallic glasses(BMGs)with good glass-forming ability(GFA)and high specific strength have been *** different alloying routes and content of Fe,it is found that these alloys exhibit different GFA and mechanical *** effects of Fe addition on the GFA and mechanical properties of Ti-Zr-Be alloy are systemically *** possible mechanisms for the improvement or damage to the GFA by addition of Fe can be interpreted in view of the mixing enthalpy,atomic size differences and electronegativity differences of the alloys,while the mechanical properties strongly depend on the Poisson’s ratio and free volume *** experimental results also show that alloying technology is an effective method to improve the GFA and mechanical properties of Ti-Zr-Be glassy alloy.
