Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>We report a new Ti₄₀Zr₂₆Be₂₈Fe₆ bulk metallic glass designed by slightly decreasing Ti/Zr concentration ratio based on the newly developed Ti₄₁Zr₂₅Be₂₈Fe₆ bulk metallic glass. The Ti₄₀Zr₂₆Be₂₈Fe₆ glassy alloy exhibits high thermal stability and the width of the supercooled liquid region for this alloy is up to 100 K. By conventional copper mold suction casting method, Ti₄₀Zr₂₆Be₂₈Fe₆ fully glassy rod with a diameter of 10 mm can be successfully obtained. Ti₄₀Zr₂₆Be₂₈Fe₆ glassy alloy also possesses excellent mechanical properties such as a high specific strength of 4.03 × 10⁵ Nm kg⁻¹ and an obvious compressive plastic strain of 7.4%, which make it possible to be used as novel aerospace materials.</p> </abstract>
