IMPROVED PRODUCTION OF POWDER METALLURGY ITEMS.
Abstract
This report describes and discusses the results of exn tests made on TZM, Inco 713C, Udimet 700, and PH15-7Mo superalloys, and contains an assessment of some superalloy powders atomized on a pilot-plant scale. TZM and PH15-7Mo can readily be extruded, but some difficulties are encountered with Udimet 700 and Inco 713C, prob ably 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 argon-melted stock appear to be similar to those made from vacuum-melted stock and considerably less expensive. (Author)
