Abstract
Small-angle scattering from carbide and gamma-prime precipitates has been observed in a Nimonic PE16 alloy. The size, density and volume fraction of the carbide and gamma-prime precipitates have been evaluated for different aging times and temperatures. The growth kinetics of the gamma-prime precipitates were constant with the theory of coarsening. The chemical composition of the gamma-prime precipitates was found to be Ni3Al0.6Ti0.4.
