This book was released on 1968 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: On grinding in pure water, zirconium, tantalum iron and stainless-steel powders were extensively comminuted and simultaneously oxidized with hydrogen release, whereas nickel, copper, and silver powders did not react with water and their particle sizes increased. On grinding nickel, copper, and silver in water pressurized with oxygen nickel and copper became extensively comminuted and were oxidized, whereas silver did not react with oxygen and its particle size increased. From these results and other considerations, it is hypothesized that for extensive comminution of ductile metals and alloys to occur on grinding they must react with the grinding media.

Available in PDF, EPUB and Kindle. Book excerpt: "In this document, one of a series dealing with specialized processes, the methodology and results of powder metallurgy are described so potential users can evaluate their worth in non-aerospace applications. This report discusses the various techniques by which powders can be produced, as pure metals or as alloys; it explains the methods by which these powders can be formed into the final parts, and further processing that may be necessary to meet the specific requirements spelled out by the user. The NASA developments are detailed, and references are provided for those who wish to obtain further information characteristic of any methodology. Compiled by experts associated with the Franklin Institute Research Laboratories, the document should be of value to manufacturing establishments, and to investigators in such areas as high strength, high temperature service, or the resistance of materials to cryogenic temperatures."--Foreword.
