Abstract
Various experimental aspects regarding the chill block melt-spinning of nickel-base superalloy ribbons have been investigated. High speed movies have been used to characterize the process, which is found to obey empirical equations already established for amorphous and low melting temperature crystalline alloys. Extensive characterization of ribbons formed has been used to assess variations in solidification rate caused by the adjustment of process parameters. Various ribbon microstructures are related to the cooling rate at local points within the ribbon during melt-spinning and are explained in terms of the effects of limited sample-substrate wetting and ribbon thickness. Theoretical and experimental factors affecting microstructural development are discussed.
