Abstract

1,247,356. Sintered Ni-Al composites. CABOT CORP. Dec. 5, 1968 [Dec. 6, 1967], No. 57813/68. Headings C7A and C7D. A sintered composite material consists of 2 to 20% A1 with the balance being Ni and has a micro-structure in which a predominant amount is in the form of a discontinuous, fibre-like, interlocked polycrystalline structure containing a solid solution of Al in Ni, and Ni a Al of which a part is present as a dispersed precipitate. The composite may be modified by the inclusion of Al 2 O 3 with a combined oxygen content of 0À1 to 3% and/or one or more of Cr up to 20%, Fe up to 25%, La up to 3%, Mo up to 15%, Nb up to 5%, Re up to 5%, Si up to 1À5%, Sn up to 6%, Ta up to 10%, Ti up to 10%, W up to 15%, Y up to 3%, Zn up to 6% and Zr up to 4%, replacing a minor part of the Ni. T be composites are made by blending the appropriate powders together; compacting and deforming the mixture to give elongated metal particles; heating the compact (e. g. to 600 to 1000‹C. ) to initiate a self-sustaining exothermic reaction and produce an interlocked polycrystalline fibre-like material; and then hotworking the composite (e. g. by rolling) at 900 to 1350‹C. to give the final required microstructure.
