| Abstract | Rapidly solidified Ni–Nb–Zr alloys in a ribbon form with a thickness of about 20 mm were prepared by a single roller melt-spinning technique. Amorphous alloys were formed in the composition range of 20 to 75 at%Ni, 0 to 60 at%Nb and 0 to 80 at%Zr. Furthermore, glassy alloys were also synthesized in the range of 50 to 70 at%Ni, 5 to 35 at%Nb and 5 to 45 at%Zr. The maximum temperature interval of the supercooled liquid region was 51K for Ni60Nb20Zr20 alloy. The tensile fracture strength and Vickers hardness of the glassy Ni60Nb20Zr20 alloy are 2160MPa and 700, respectively. Wide ribbons with a width of 50mm of amorphous Ni42Nb28Zr30 and glassy Ni60Nb20Zr20 alloys were produced at a circumferential velocity of the copper roller of 20m/s. |
