Powder metallurgy processes inventions

20090280022 - Titanium, titanium alloy and niti foams with high ductility: A method for manufacturing a high ductility Ti-, Ti-alloy or NiTi-foam, meaning a compression strain higher than 10%, includes: preparing a powder suspension of a Ti-, NiTi- or Ti-alloy powder, bringing the said powder suspension into a desired form by gelcasting to form a green artefact. The method also includes... Agent: Merchant & Gould PC

20090263266 - L12 strengthened amorphous aluminum alloys: An improved amorphous aluminum alloy having high strength, ductility, corrosion resistance and fracture toughness is disclosed. The alloy has an amorphous phase and a coherent L12 phase. The alloy has nickel, cerium, at least one of scandium, erbium, thulium, ytterbium, and lutetium; and at least one of gadolinium, yttrium, zirconium,... Agent: Kinney & Lange, P.A.

20090263267 - Method for manufacturing a porous oil-impregnated revolving shaft assembly: A method for manufacturing a porous oil-impregnated revolving shaft assembly includes following steps: 1) offering an amount of metal powder, a particle diameter of the metal powder ranging from 1 μm to 150 μm; 2) offering a mold cavity and filling the metal powder in the mold cavity to form...
