Abstract: A fiber reinforced glass matrix composite has a glass matrix or glass ceramic and a plurality of primary and secondary reinforcing fibers dispersed in the matrix. The primary fibers may be continuous or discontinuous. The secondary fibers are discontinuous. The secondary reinforcing fibers which are shorter than the primary fibers fill regions of the matrix not filled with the primary reinforcing fibers. The composite may be made by uniformly distributing the secondary reinforcing fibers in a dispersant. A glass powder is mixed in a carrier liquid to create a slurry and the secondary reinforcing fibers and dispersant are slowly added to the slurry so the fibers uniformly disperse as they are added. A binder is also added to the slurry. A continuous fiber is impregnated with the slurry and the impregnated fiber is dried to remove the carrier liquid. The impregnated yarn is cut to a suitable length and molded by a suitable molding method to form a fiber reinforced glass matrix composite.

Abstract: Heat Treatment of Single Crystals Concepts relating to the heat treatment of single crystal superalloy articles are disclosed. A first concept is the use of a heat treatment sequence which includes incipient melting of the article being heat treated followed my one or more steps which essentially heal the incipient melting damage. A second concept relates to the treatment of previously heat treated single crystal articles which have incipient melting. Methods are disclosed for healing this damage and for recovering the mechanical properties of such articles. A third concept disclosed is a particular cycle which permits effective heat treatment of a specific single crystal alloy composition.

Abstract: Corrosion resistant, high strength, superalloy single crystal articles are described. Starting with a nominal composition of 11.75% Cr, 9% Co, 1.75% Mo, 4.5% W, 2.5% Ta, 2.5% Al, 4% Ti, balance essentially nickel, intentional additions are made of carbon and extra tantalum. From 0.05-0.15% carbon is added along with sufficient tantalum to combine with the carbon to form tantalum carbon. The resultant articles have substantially improved hot corrosion resistance and creep properties.

Abstract: The alloy comprises 13-15.6% Cr 5-15% Co 2.5-5% Mo 3-6% W 4-6% Ti 2-4% Al balance Ni with no intentional additions of C, B or Zr. Single crystal articles of the above composition display a resistance to hot corrosion and a rupture life at least 3 x and 5 x respectively that of a conventional polycrystalline material of similar composition but with C, B and Zr additions.
