Filed:

Mar 4, 2004

Appl. No.:

10/793558

Inventors:

James D. Cotton - Issaquah WA, US

Assignee:

The Boeing Company - Seattle WA

International Classification:

B23K 1/00

US Classification:

266230, 266 45, 266227

Abstract:

A system for filtering hard alpha inclusions from a reactive metal alloy, such as titanium, is provided. The system includes a vessel, a receptacle and a filter. The vessel is capable of holding the reactive metal alloy in a molten form, and can pour the molten reactive metal alloy. The receptacle is for receiving the molten reactive metal alloy poured from the vessel. And to prevent at least some hard alpha inclusions from entering the receptacle, the filter is disposed between the vessel and the receptacle such that the molten reactive metal alloy passes therethrough before being received by the receptacle. The filter includes a frame, and a porous surface that is disposed within the frame. The porous surface defines openings that are sized to permit the reactive metal alloy in molten form to pass therethrough while capturing hard alpha inclusions.

International Classification:

C22F 1/18

US Classification:

148670, 148671

Abstract:

A method is provided for improving the machinability of a titanium alloy includes heating the alloy at a temperature and time period that imparts to the alloy a microstructure having between about 10 and 15 vol. % alpha phase in a beta phase matrix. According to one embodiment, the alloy is thereafter annealed at a temperature lower than the temperature for the initial heating step, and for a duration that is longer than the time period for the initial heating step.

International Classification:

G06F 17/50

US Classification:

700106

Abstract:

A computer implemented method, apparatus, and computer usable program code for designing a product using technology readiness levels for materials. Entries identifying materials and technology readiness levels for the materials are stored in a database. A first design is developed using a first material selected from the database, wherein the first material has a first technology readiness level identified from the database. A second design is developed using a second material selected from the database, wherein the second material has a second technology readiness level identified from the database. The first design is compared to the second design using the first technology readiness level and the second technology readiness level to form a comparison. A selection is made between the first design and the second design using the comparison.

International Classification:

B22F 3/12
B22F 1/00

US Classification:

419 13, 419 33

Abstract:

There is provided cryogenic milled nanophase copper alloys and methods of making the alloys. The alloys are fine grained having grains in the size range from about 2 to about 100 nanometers, and greater. The nanophase alloys possess desirable physical properties stemming from the fine grain size, such as potentially high strength. Some embodiments of the cryogenic milled copper alloys may also be tailored for ductility, toughness, fracture resistance, corrosion resistance, fatigue resistance and other physical properties by balancing the alloy composition. In addition, embodiments of the alloys generally do not require extensive or expensive post-cryogenic milling processing.

Abstract:

A method and apparatus for detection of rare earth metal oxide inclusions in non-magnetic metal. The method utilizes a D. C. magnetic search field coupled with a magnetic field sensor for detecting the response of a rare earth metal oxide casting fragment inclusion through the bending and amplification of the ambient magnetic field at the defect location.
