Abstract: A method for gas atomization of a titanium alloy, nickel alloy, or other alumina (Al2O3)-forming alloy wherein the atomized particles are exposed as they solidify and cool in a very short time to multiple gaseous reactive agents for the in-situ formation of a passivation reaction film on the atomized particles wherein the reaction film retains a precursor halogen alloying element that is subsequently introduced into a microstructure formed by subsequent thermally processing of the atomized particles to improve oxidation resistance.

Abstract: A method of selectively oxidizing one or more target metals in an alloy comprising target and non-target metals is provided. The method comprises the steps of: i) melting the alloy and exposing the molten alloy to simultaneous fragmentation and oxidation in the presence of an oxygenated atomizing gas under conditions sufficient to yield an oxidation potential that oxidizes the one or more target metals in the alloy and does not oxidize the non-target metal(s); and ii) allowing the treated alloy to solidify. The method is useful to purify a non-target base metal. The method is also useful to produce a metal compound comprising a desired content of one or more oxidized target metals above the theoretical maximum generally achieved by thermal plasma spray surface coating applications.

Abstract: There is a problem that when a silver powder sintering paste that is substantially free from resin is used, an organic solvent used as a dispersion medium bleeds, which results in contamination and wire bonding defects. In order to solve the problem, provided is a metal powder sintering paste that contains, as a principal component, silver particles having an average particle diameter (a median diameter) of 0.3 μm to 5 μm and further contains an anionic surfactant but is substantially free from resin.

Abstract: A method for manufacturing a powder magnetic core using a soft magnetic material powder, wherein the method has: a first step of mixing the soft magnetic material powder with a binder, a second step of subjecting a mixture obtained through the first step to pressure forming, and a third step of subjecting a formed body obtained through the second step to heat treatment. The soft magnetic material powder is an Fe—Cr—Al based alloy powder comprising Fe, Cr and Al. An oxide layer is formed on a surface of the soft magnetic material powder by the heat treatment. The oxide layer has a higher ratio by mass of Al to the sum of Fe, Cr and Al than an alloy phase inside the powder.
