PRODUCTION OF EXTRUSION BILLET OF HIGH TEMPERATURE AIRCRAFT ALLOYS BY POWDER METALLURGY. First Interim Engineering Report, Phase I-June 15, 1959-October 31, 1959
A commentary on the various available methods for the production of extrusion billets from metal powder and their relative capabilities are given. Included is a discussion of the current sources of powder, the type of powder available, and a brief description of the methods employed in their production. A revisw of alloys suituble for study in Phase II and Phase III of the program is presented, based upon the prsliminary survey of alloys currently being applied in the programs of the Air Force which are adaptable to the processes selected for this project. A description is included of some preliminary work on compaction and extrusion of Udimet powders. Tensile properties comparable to those obtained with wrought material are reported for bar stock extruded from a powder billet of Udimet 500. (auth)
