摘要：

We report a new 40Zr26Be28Fe6 bulk metallic glass designed by slightly decreasing 41Zr25Be28Fe6 bulk metallic glass. 40Zr26Be28Fe6 glassy alloy exhibits high thermal stability and the width of the supercooled liquid region for this alloy is up to 100K. By conventional copper mold suction casting method, 40Zr26Be28Fe6 fully glassy rod with a diameter of 10mm can be successfully obtained. 40Zr26Be28Fe6 glassy alloy also possesses excellent mechanical properties such as a high specific strength of 4.03x10(5)Nmkg(-1) and an obvious compressive plastic strain of 7.4%, which make it possible to be used as novel aerospace materials.
