Abstract: A metal powder for use in a metal laser-sintering wherein a three-dimensional shaped object is produced by irradiating a powder layer of the metal powder with a light beam to form a sintered layer and thereby laminating the sintered layers. The metal powder of the present invention is characterized in that it comprises an iron-based powder and at least one kind of powder selected from the group consisting of a nickel powder, a nickel-based alloy powder, a copper powder, a copper-based alloy powder and a graphite powder; and the iron-based powder has been annealed. In such metal powder, the iron-based powder is in a softened state due to the annealing treatment thereof. Accordingly, the use of the metal powder in a metal laser-sintering process makes it possible to reduce a machining resistance attributable to the residual metal powder adherent to the surface of the shaped object, which leads to an achievement of an extended lifetime of a machining tool.

Abstract: An iron-chromium based brazing filler metal is provided which exhibits an excellent wetting behavior on a stainless steel base material. The brazing filler metal produces a brazed joint which exhibits high strength and good corrosion resistance. The brazing filler metal is suitable for brazing stainless steel and other materials where corrosion resistance and high strength is required. Typical examples of applications are heat exchangers and catalytic converters. The iron-chromium based brazing filler metal powder according to the invention comprises: between 11 and 35 wt % chromium, between 0 and 30 wt % nickel, between 2 and 20 wt % copper, between 2 and 6 wt % silicon, between 4 and 8 wt % phosporous, between 0-10 wt % manganese, and at least 20 wt % iron.

Abstract: A Ni—Fe—Cr—Mo alloy containing a small amount of Cu and correlated percentages of Nb, Ti and Al to develop a unique microstructure to produce 145 ksi minimum yield strength. The unique microstructure is obtained by special annealing and age hardening conditions, by virtue of which the alloy has an attractive combination of yield strength, impact strength, ductility, corrosion resistance, thermal stability and formability, and is especially suited for corrosive oil well applications that contain gaseous mixtures of carbon dioxide and hydrogen sulfide. The alloy comprises in weight percent the following: 0-15% Fe, 18-24% Cr, 3-9% Mo, 0.05 3.0% Cu, 3.6-6.5% Nb, 0.5-2.2% Ti, 0.05-1.0% Al, 0.005-0.040% C, balance Ni plus incidental impurities and a ratio of Nb/(Al+Ti) in the range of 2.5-7.5. To facilitate formability, the composition range of the alloy is balanced to be Laves phase free.

Abstract: The invention discloses a soft magnetic amorphous alloy and a soft magnetic nanocomposite alloy formed from the amorphous alloy. Both alloys comprise a composition expressed by the following formula: (Fe1-x-yCoxMy)100-a-b-cTaBbNc where, M is at least one element selected from the group consisting of Ni and Mn; T is at least one element selected from the group consisting of Nb, W, Ta, Zr, Hf, Ti, Cr, Cu, Mo, V and combinations thereof, and the content of Cu when present is less than or equal to 2 atomic %; N is at least one element selected from the group consisting of Si, Ge, C, P and Al; and 0.01?x+y<0.5; Q?y?0.4; 1<a<5 atomic %; 10<b<30 atomic %; and 0<c<10 atomic %. A core, which may be used in transformers and wire coils, is made by charging a furnace with elements necessary to form the amorphous alloy, rapidly quenching the alloy, forming a core from the alloy; and heating the core in the presence of a magnetic field to form the nanocomposite alloy.
