Abstract
Rapidly solidified Ni-Nb-Zr alloys in a ribbon form with a thickness of about 20 μm were prepared by a single roller melt-spinning technique. Amorphous alloys were formed in the composition range of 20 to 75at%Ni, 0 to 60at%Nb and 0 to 80at%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 1was 51 K for Ni60Nb20Zr20 alloy. The tensile fracture strength and Vickers hardness of the glassy Ni60Nb20Zr20 alloy are 2160 MPa and 700, respectively. Wide ribbons with a width of 50 mm of amorphous Ni42Nb28Zr30 and glassy Ni60Nb20Zr20 alloys were produced at a circumferential velocity of the copper roller of 20 m/s.
