Available in PDF, EPUB and Kindle. Book excerpt: Two methods were compared for preparing dispersion-strengthened nickel- and cobalt-base alloys. A technique of selectively reducing intimately mixed oxides, which were prepared by atomizing and drying a solution of the components, was more successful than one involving the coating of dispersoid particles with the matrix by vapor deposition. The conditions were determined for preparing Ni-15Mo-4ThO2 and Co-15Mo-4ThO2 powders by selective reduction. Hot pressing, hydrogen sintering, and powder rolling were evaluated for powder consolidation. The conditions for successful rolling, extrusion, and forging were investigated for Ni-15Mo-4ThO2. Process temperatures above 1200C promoted ThO2 growth to 400-500A. Deformation-anneal sequences were critical to good strength at elevated temperatures. Ultimate strengths of 21 ksi at 1800F were obtained and higher strengths seem possible. Molybdenum considerably improved the matrix strength to at least 1400F.

This book was released on 1977 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present study describes the development of an Oxide Dispersion Strengthened, Cobalt base alloy with the nominal composition of Co-20Ni-18Cr-4.5A1-1.75 Y2O3. The alloy was produced in extruded form from mechanically attrited powder. In the first part of this study a series of small scale (3in. dia.) extrusions were produced in order to evaluate various compositional and processing parameters. Based upon this study a single powder composition and three sets of extrusion parameters were chosen for use with full scale 7in. diameter extrusion billets. Dynamic (Mach 0.3), 2100 F oxidation tests showed the material to have excellent surface stability under these conditions, and hot corrosion testing at 1650 F showed it to be slightly superior to the analogous Ni base O.D.S. materials in this latter type of environment.
