在高性能结构材料的发展中，实现轻质、高强与良好塑性的平衡始终是材料设计的重要挑战。钛基金属玻璃因其极高的比强度而备受关注，但强度与塑性之间的固有矛盾长期限制了其应用潜力。本文基于前期由准晶Ti40Zr40Ni20衍生的(Ti40Zr40Ni20)72Be28块体金属玻璃体系，通过引入少量Al元素实现了性能的协同优化。结果表明，((Ti40Zr40Ni20)72Be28)97Al3块体金属玻璃的比强度高达5.34 × 105N·m·kg-1，创造了Ti基金属玻璃的新纪录，同时塑性应变达到了13%，突破了金属玻璃比强度-塑性的性能界限。结构分析表明，Al的微合金化有效继承并调控了源自准晶相的短程有序结构特征，从而实现了强度与塑性的协同提升。本研究为Ti基块体金属玻璃的成分设计及其在轻量化结构材料领域的应用提供了新的思路。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 exhibits an ultrahigh specific strength of 5.34 × 105 N·m·kg-1, setting a new record for Ti-based BMGs, together with a plastic strain of 13%, breaking the conventional strength–plasticity limitation of BMGs. Structural analyses reveal that Al microalloying effectively inherits and modulates the short-range order originating from the quasicrystalline structure, thereby achieving the observed synergistic enhancement in both strength and plasticity. This work provides new insights into composition design and lightweight structural applications of Ti-based BMGs.
