Dynamic Compaction of Rapidly Solidified Nickel-Base Superalloys (Rapid Solidification, Powder Metallurgy, Hot Isostatic Pressing, Consolidation, Precipitation)

Rapid solidification of an experimental nickel-base superalloy was achieved using centrifugal atomization, chill-block melt-spinning and laser surface melting. Transmission electron microscopy was utilized to characterize the various microstructures obtained in terms of growth morphology, segregation profiles, (gamma)' size and distribution of secondary hardening phases. The response of melt-spun ribbon to thermal treatment was determined and utilized to evaluate the microstructures observed in consolidated material.
