US Patent:

47341300, Mar 29, 1988

Filed:

Aug 10, 1984

Appl. No.:

6/639300

Inventors:

Colin M. Adam - Morristown NJ
Kenji Okazaki - Lexington KY
David J. Skinner - Flanders NJ
Robert G. Corey - Murrells Inlet SC

Assignee:

Allied Corporation - Morris Township, Morris County NJ

International Classification:

C22C 104

US Classification:

75 68A

Abstract:

The present invention provides a method for producing an aluminum alloy which includes the step of carbothermically reducing an aluminous material to provide an alloy consisting essentially of the formula Al. sub. bal TM. sub. d Si. sub. e, wherein TM is at least one element selected from the group consisting of Fe, Ni, Co, Ti, V, Zr, Cu and Mn, "d" ranges from about 2-20 wt %, "e" ranges from about 2. 1-20 wt %, and the balance is aluminum and incidental impurities. The alloy is placed in the molten state and rapidly solidified at a quench rate of at least about 10. sup. 6 K/sec to produce a rapidly solidified alloy composed of a predominately microeutectic and/or microcellular structure.
