摘要:
The invention provides a method and system for secure information sharing. An information sharing system includes a database system consisting of one or more databases working in coordination with the information sharing system configured to store one or more unique information bundles for a user. The one or more unique information bundles are generated by encapsulating/encoding a plurality of information items associated with the user. The information sharing system further includes an information sharing module configured to share one or more unique information bundles with one or more parties selectively on a need to know basis when needed. The information sharing module is further configured to share one or more Trusted Delivery Agent (TDA) IDs associated with one or more TDAs.
摘要:
A method of making composites of bulk-solidifying amorphous alloys, and articles made thereof, containing at least one type or reinforcement material, wherein the composite material preferably comprises a high volume fraction of reinforcement material and is fully-dense with minimum porosity are provided.
摘要:
Compositions for forming Au-based bulk-solidifying amorphous alloys are provided. The Au-based bulk-solidifying amorphous alloys of the current invention are based on ternary Au—Cu—Si alloys, and the extension of this ternary system to higher order alloys by the addition of one or more alloying elements. Additional substitute elements are also provided, which allow for the tailoring of the physical properties of the Au-base bulk-solidifying amorphous alloys of the current invention.
摘要:
A golf club is made of a club shaft and a club head. Either the club shaft or the club head is made at least in part of a in-situ composite of bulk-solidifying amorphous alloy. The weights of the various club heads of a set, which have different volumes, may be established by varying the compositions and thence the densities of the bulk-solidifying amorphous alloys.

Sharp-edged cutting tools and a method of manufacturing sharp-edged cutting tools wherein at least a portion of the sharp-edged cutting tool is formed from a bulk amorphous alloy material are provided.
摘要:
A reinforcement-containing metal-matrix composite material is formed by dispersing pieces of reinforcement material throughout a melt of a bulk-solidifying amorphous metal and solidifying the mixture at a sufficiently high rate that the solid metal matrix is amorphous. Dispersing is typically accomplished either by melting the metal and mixing the pieces of reinforcement material into the melt, or by providing a mass of pieces of the reinforcement material and infiltration of the molten amorphous metal into the mass. The metal preferably has a composition of about that of a eutectic composition, and most preferably has a composition, in atomic percent, of from about 45 to about 67 percent total of zirconium plus titanium, from about 10 to about 35 percent beryllium, and from about 10 to about 38 percent total of copper plus nickel.

A torsionally reacting spring, such as a helical spring, a torsion bar, or a torsion tube, requires the ability to torsionally deform elastically during service and return to its original, undeformed shape. The torsionally reacting spring is made of a bulk-deforming amorphous alloy which may be cooled from the melt at a cooling rate of less than about 500.degree. C. per second, yet retain an amorphous structure. A preferred bulk-solidifying amorphous alloy has a composition, in atomic percent, of from about 45 to about 67 percent total of zirconium plus titanium, from about 10 to about 35 percent beryllium, and from about 10 to about 38 percent total of copper plus nickel, plus incidental impurities, the total of the percentages being 100 atomic percent.

A diamond-containing metal-matrix composite material is formed by dispersing pieces of diamond throughout a melt of a bulk-solidifying amorphous metal and solidifying the mixture. The mixture may then be remelted and resolidified at a rate sufficiently high that the metal matrix retains an amorphous structure upon cooling. The metal preferably has a composition of about that of a eutectic composition, and most preferably has a composition, in atomic percent, of from about 45 to about 67 percent total of zirconium plus titanium, from about 10 to about 35 percent beryllium, and from about 10 to about 98 percent total of copper plus nickel. The diamond is preferably low-grade or artificial diamond.
