Abstract

Main development directions are discussed for granular metallurgy of high-temperature nickel alloys. The development provides refinement of produced materials as well as stability increasing for their operational properties. These enhancements are related to various stages of the production cycle including manufacturing of granules; filling, compaction and sealing of granules in capsules; separations, dissemination, gas-static compaction of capsules and deformation by means of new chrome-based stamp materials.
