Abstract

It has been found that alloying with Cu element could significantly enhance the glass-forming ability (GFA) of Ti-Zr-Be-Fe alloy. As a result, a series of centimeter-scale (Ti₄₁Zr₂₅Be₂₈Fe ₆)_100-xCu_x (x = 0-20 at.%) bulk metallic glasses (BMGs) have been developed. Especially for those with x = 7-13 at.% Cu content, the critical size is larger than 20 mm. Among these Ti-based BMGs, (Ti₄₁Zr₂₅Be₂₈Fe₆) ₉₁Cu₉ (also noted as Ti_37.31Zr _22.75Be_25.48Fe_5.46Cu₉) glassy alloy exhibits superior GFA with a critical size larger than 32 mm, which is the largest size of Ti-based BMGs ever reported so far. The enhancement of the GFA is suggested to arise from the Cu addition-induced decrease in both the liquidus temperature and the Gibbs energy difference between the undercooled liquid and the crystalline phases of Ti-Zr-Be-Fe alloy. In addition to its superior GFA, the lightweight (Ti₄₁Zr₂₅Be₂₈Fe ₆)₉₁Cu₉ alloy also exhibits a remarkable high specific strength of 3.7 × 10⁵ N m kg^-1 and an apparent plastic strain of 1.2%.
