摘要:
A method for producing an aluminum foam product wherein reactive gas producing particles are introduced into an aluminum alloy melt under controlled conditions and subjected to agitation to induce the production of foam-stabilizing by-products, and, under certain conditions, the production of gases used to produce the molten metal foam itself. Foam products produced through this method have intrinsically formed metal oxides and other solid particles dispersed therein and are devoid of the large extrinsically added stabilizing ceramic additions traditionally used in the production of aluminum foams. The invention claims a rapid, single step method for producing an inoculated, foamable melt using low cost precursor materials.

An article includes a microscale composite material having a matrix with more titanium than any other element, and a dispersion of titanium boride particles in the matrix. At least about 50 volume percent of the titanium boride particles have a maximum dimension of less than about 2 micrometers.
摘要:
An article made of constituent elements is prepared by furnishing at least one nonmetallic precursor compound, wherein all of the nonmetallic precursor compounds collectively contain the constituent elements. The constituent elements include a titanium-base metallic composition, boron present at a level greater than its room-temperature solid solubility limit, and, optionally, a stable-oxide-forming additive element present at a level greater than its room-temperature solid solubility limit. The precursor compounds are chemically reduced to produce a material comprising a titanium-base metallic composition having titanium boride particles therein, without melting the titanium-base metallic composition. The titanium-base metallic composition having the titanium boride particles therein is consolidated without melting.
