We report a new Ti 40 Zr 26 Be 28 Fe 6 bulk metallic glass designed by slightly decreasing Ti/Zr concentration ratio based on the newly developed Ti 41 Zr 25 Be 28 Fe 6 bulk metallic glass. The Ti 40 Zr 26 Be 28 Fe 6 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, Ti 40 Zr 26 Be 28 Fe 6 fully glassy rod with a diameter of 10 mm can be successfully obtained. Ti 40 Zr 26 Be 28 Fe 6 glassy alloy also possesses excellent mechanical properties such as a high specific strength of 4.03 × 10 5 Nm kg −1 and an obvious compressive plastic strain of 7.4%, which make it possible to be used as novel aerospace materials.
