| Abstract: | The rod Cu_ 50Zr_ 42Al_8 bulk amorphous alloys with smooth surface and typical metal lightness were successfully prepared by copper-mold suction casting combining with magnetic-suspending melting method.The maximum diameter of prepared rod Cu_ 50Zr_ 42Al_8 bulk amorphous alloys is less than 5 mm under the above experimental conditions.Cu_ 50Zr_ 42Al_8 bulk amorphous alloys have excellent glass-forming ability with glass transition temperature (T_g) 723 K,crystallization temperature (T_x) 773 K,supercooled temperature 50 K and reduced glass transition temperature (T_ rg) 0.753. |
