  • Patent number: 6669899
    Abstract: A ductile particle-reinforced amorphous matrix composite characterized in that ductile powder is dispersed into amorphous matrix and the mixture is plastically worked to be consolidated and a method for manufacturing the same are provided. The amorphous powder includes any alloy, which can be produced in the form of amorphous structure and which is selected from the group consisting of Ni-, Ti-, Zr-, Al-, Fe-, La-, Cu- and Mg-based alloys. The method for manufacturing a ductile particle-reinforced amorphous matrix composite, the method comprising steps of preparing a mixture consisting of amorphous powder and ductile powder, obtaining a billet by compacting the mixture in a hermetically sealing condition, and plastic working the mixture by processing the billet at the temperature in the super-cooled liquid region of the amorphous alloy.

  • Patent number: 6325868
    Abstract: Disclosed are nickel-based amorphous alloy compositions, and particularly quaternary nickel-based amorphous alloy compositions containing nickel, zirconium and titanium as main constituent elements and additive Si or P, the quaternary nickel-zirconium-titanium-silicon alloy compositions comprising nickel in the range of 45 to 63 atomic %, zirconium plus titanium in the range of 32 to 48 atomic % and silicon in the range of 1 to 11 atomic %, and being represented by the general formula: Nia(Zr1−xTix)bSic. Also, at least one kind of element selected from the group consisting of V, Cr, Mn, Cu, Co, W, Sn, Mo, Y, C, B, P, Al can be added to the alloy compositions in the range of content of 2 to 15 atomic %. The quaternary nickel-zirconium-titanium-phosphorus alloy compositions comprising nickel in the range of 50 to 62 atomic %, zirconium plus titanium in the range of 33 to 46 atomic % and phosphorus in the range of 3 to 8 atomic %, and being represented by the general formula: Nid(Zr1−yTiy)ePf.
