A pre-alloyed nickel-titanium alloy is melted and atomized to form molten nickel-titanium alloy particles. The molten nickel-titanium alloy particles are cooled to form nickel-titanium alloy powder. The nickel-titanium alloy powder is consolidated to form a fully-densified nickel-titanium alloy preform that is hot worked to form a nickel-titanium alloy article. Any second phases present in the nickel-titanium alloy article have a mean size of less than 10 micrometers measured according to ASTM E1245-03 (2008) or an equivalent method.Type: ApplicationFiled: June 3, 2013Publication date: October 10, 2013Applicant: ATI PROPERTIES, INC.Inventor: C.

Publication number: 20130213168Abstract: The invention relates to a toothed wheel arrangement (1) comprising a main toothed wheel (2) and a toothed wheel (4) that can be rotated relative thereto in the circumferential direction (3), wherein the main toothed wheel (2) comprises a toothed wheel body (25) on which a hub (5) is arranged in a projecting manner in the axial direction so as, firstly, to accommodate a shaft and, secondly, to arrange the rotatable toothed wheel (4) thereon, for which purpose the rotatable toothed wheel (4) has a cutout (17) coaxial to an axially extending center axis of the main toothed wheel (2), and wherein the main toothed wheel (2) is connected to the rotatable toothed wheel (4) by means of a bayonet fastening (14). The bayonet fastening (14) is formed between the hub (5) and the rotatable toothed wheel (2) and/or between the hub (5) and a spring element (9) bearing on the rotatable toothed wheel (4).Type: ApplicationFiled: September 27, 2011Publication date: August 22, 2013Applicant: MIBA SINTER AUSTRIA GMBHInventors: Helmut Buchleitner, Karl Dickinger, Alexander Mueller, Wolfgang Siessl

Publication number: 20130218281Abstract: A method of pressure forming a brown part from metal and/or ceramic particle feedstocks includes: introducing into a mold cavity or extruder a first feedstock and one or more additional feedstocks or a green or brown state insert made from a feedstock, wherein the different feedstocks correspond to the different portions of the part; pressurizing the mold cavity or extruder to produce a preform having a plurality of portions corresponding to the first and one or more additional feedstocks, and debinding the preform. Micro voids and interstitial paths from the interior of the preform part to the exterior allow the escape of decomposing or subliming backbone component substantially without creating macro voids due to internal pressure. The large brown preform may then be sintered and subsequently thermomechanically processed to produce a net wrought microstructure and properties that are substantially free the interstitial spaces.Type: ApplicationFiled: April 30, 2010Publication date: August 22, 2013Applicant: ACCELLENT INC.Inventors: Mark W.
