Abstract
Achieving a balance between low density, high strength, and good ductility remains a major challenge in the development of structural materials. Ti-based bulk metallic glasses (BMGs) have attracted considerable attention due to their exceptionally high specific strength. However, the intrinsic strength–plasticity trade-off has hindered their practical applications. Based on a quasicrystal-derived structural heredity and minor-element microalloying, this work realizes a synergistic enhancement of specific strength and plasticity in Ti-based BMGs. The resulting ((Ti₄₀Zr₄₀Ni₂₀)₇₂Be₂₈)₉₇Al₃ BMGs demonstrate an ultrahigh specific strength of 5.34 × 10⁵ N·m·kg^–1, establishing a new record for Ti-based BMGs, along with a plastic strain of 13%, breaking through the traditional strength–plasticity limitation of BMGs. Structural analyses show that Al microalloying effectively inherits and modulates the short-range order derived from quasicrystalline structures, thereby achieving an observed synergistic enhancement in both strength and plasticity. This work provides new insights into composition design and lightweight structural applications of Ti-based BMGs.
