7/467810

Inventors:

James R. Crum - Ona WV

Edward L. Hibner - Ona WV

Assignee:

Inco Alloys International, Inc. - Huntington WV

International Classification:

C22F 110

US Classification:

148 13

Abstract:

A homogenizaton heat treatment for enhancing crevice and pitting corrosion resistance minimizes the formation of Mu phase in nickel-base alloys of high combined percentages of chromium, e. g. , 19 to 23% and molybdenum, e. g. , 14 to 17%, particularly together with tungsten. Also described is an advantageous alloy composition containing less than 2. 5% iron, low carbon and a titanium to carbon ratio greater than 1 which is particularly adapted to be effectively treated by the homogenization heat treatment.

Appl. No.:

7/071654

Inventors:

Jon M. Poole - Huntington WV
Lindy J. Curtis - Huntington WV

Assignee:

Inco Alloys International, Inc. - Huntington WV

International Classification:

B22F 100

US Classification:

419 33

Abstract:

A method for pickling and consolidating water atomized metallic powders to reduce surface oxides. The technique includes introducing the powder into an acid bath--preferably nitric acid and hydrofluoric acid, rinsing the powder, introducing the powder into an alkaline bath, rinsing the powder and then consolidating the powder into a workpiece. Alternatively, the powder can be additionally introduced into a second acid bath and/or placed into a finishing boric acid bath before consolidation.

Appl. No.:

6/792033

Inventors:

Jon M. Poole - Huntington WV

Assignee:

Inco Alloys International, Inc. - Huntington WV

International Classification:

C22C 3200

US Classification:

419 12

Abstract:

A method for consolidating powder utilizing slurry extrusion or rolling techniques. A metallic powder, binder and boron containing activator are mixed together to form a slurry. The slurry is introduced into an active forming apparatus whereupon it is formed into an object of predetermined shape and sintered.

Inventors:

Jon M. Poole - Barboursville WV

Assignee:

Inco Alloys International, Inc. - Huntington WV

International Classification:

B22F 100

US Classification:

419 11

Abstract:

A method for utilizing a powder metallurgy ("P/M") slurry by employing water atomized metallic powders and subsequently reducing the oxide levels therein to acceptable levels. The slurry comprises a carbon containing binder. The slurry is consolidated and sintered under controlled conditions to reduce the oxide levels.

International Classification:

C22C 3000

US Classification:

75255

Abstract:

A mechanically alloyed composition of matter containing 30-40% chromium, 0-15% cobalt, 0-10% iron, 0. 2-1. 0% aluminum, 0. 3-1. 2% titanium, greater than 1-5% tantalum and/or niobium, 0. 2-1% yttria, usual processing and trace impurities, and the balance nickel.

International Classification:

H01B 1200

US Classification:

505 1

Abstract:

The invention provides a process for production of silver-containing precursor alloys to oxide superconductors, said alloys having reduced amounts of intermetallics. Powders containing metallic elemental components of an oxide superconductor are high energy milled for a predetermined amount of time to increase homogeneity of the mixed metallic elemental components of the oxide superconductor. Silver is then high energy milled into the metallic components. The mixed silver and metallic elemental components of the oxide superconductor are compacted for the silver-containing superconductor precursor. The compacted powder is preferably hot worked at a temperature of at least 50% of the precursor alloy's melting temperature in degrees Kelvin.
