The results of sintering studies on atomized superalloy powders are discussed. The time and temperature conditions for optimum sintering are defined, and the metallographic structures of the sintered materials are examined. Also, the chemical compositions and gas contents of the alloys are considered in relation to the various stages involved in the manufacture and processing of the superalloys. It is concluded that the boundary conditions for the production of superalloy billets by powder metallurgy techniques are now fairly well established.
