IMPROVED PRODUCTION OF POWDER METALLURGY ITEMS. Interim Technical Progress Report, April 1, 1963-June 30, 1963
Results of extrusion tests made on TZM, Inco 713C, Udimet 700, and PH15-- 7Mo superalloys are described. An assessment of some superalloy powders atomized on a pilot-plant scale is made. TZM and PH15--7Mo can readily be extruded, but some difficulties are encountered with Udimet 700 and Inco 713C, probably because of unsoundness in the cast extrusion billets. The pilot-plant atomized powders are fine, have irregular shape, and low green density, but very high green compact strength and hence good handling properties. Those powders made from prealloyed, high-purity melt stock have acceptable nitrogen contents but high oxygen contents. Powders atomized from argonmelted stock appear to be similar to those made from vacuum-melted stock and considerably less expensive. (auth)
