Ni-based bulk amorphous alloys in the Ni-Ti-Zr-(Si,Sn) system
|
Author(s): S. Yi, T. G. Park, D. H. Kim Center for Noncrystalline Materials, Department of Metallurgical Engineering, Yonsei University, Seoul, Korea New Ni-based bulk amorphous alloys in the alloy system Ni-Ti-Zr-(Si,Sn) were developed through systematic alloy design based upon the empirical rules for high glass forming alloys. Small additions of Si and/or Sn significantly improved the glass forming ability (GFA) of the alloys Ni57Ti23-xZr20(Si,Sn)x leading to a Ni-based bulk amorphous alloy. The amorphous ribbons of the alloys Ni57Ti23-xZr20(Si,Sn)x exhibited very high glass transition temperatures (Tg > 823 K), crystallization temperatures (Tx > 883 K), and large undercooled liquid regions (ΔTx > 50 K) implying the high GFA of the alloys. Fully amorphous rods with the diameter of up to 2 mm can be fabricated by a copper mold casting method. Development of the new Ni-based bulk amorphous alloys having high Tg, Tx, and ΔTx expands the practical applications of amorphous alloys as structural materials.
