Title: Preparation, mechanical strengths, and thermal stability of Ni-Si-B and Ni-P-B amorphous wires

Abstract

Ni-based amorphous wires with good bending ductility have been prepared for Ni/sub 75/Si/sub 8/B/sub 17/ and Ni/sub 78/P/sub 12/B/sub 10/ alloys containing 1 to 2 at. pct Al or Zr by melt spinning in rotating water. The enhancement of the wire-formation tendency by the addition of Al has been clarified to be due to the increase in the stability of the melt jet through the formation of a thin Al/sub 2/O/sub 3/ film on the outer surface. The maximum wire diameter is about 190 to 200 ..mu..m for the Ni-Si (or P)-B-Al alloys and increases to about 250 ..mu..m for the Ni-Si-B-Al-Cr alloys containing 4 to 6 at. pct Cr. The tensile fracture strength and fracture elongation are 2730 MPa and 2.9 pct for (N/sub 0.75/Si/sub 0.08/B/sub 0.17/)/sub 99/Al/sub 1/ wire and 2170 MPa and 2.4 pct for (Ni/sub 0.78/P/sub 0.12/B/sub 0.1/)/sub 99/Al/sub 1/ wire. These wires exhibit a fatigue limit under dynamic bending strain in air with a relative humidity of 65 pct; this limit is 0.50 pct for a NiSi-B-Al wire, which is higher by 0.15 pct than that of a Fe/sub 75/Si/sub 10/B/sub 15/ amorphous wire. Furthermore, the Ni-base wires do not fracture during a 180-deg bendingmore » even for a sample annealed at temperatures just below the crystallization temperature, in sharp contrast to high embrittlement tendency for Fe-base amorphous alloys. Thus, the Ni-based amorphous wires have been shown to be an attractive material similar to Fe- and Co-based amorphous wires because of its high static and dynamic strength, high ductility, high stability to thermal embrittlement, and good corrosion resistance.« less
