An in situ x-ray diffraction study of precipitation from a supersaturated solid solution: The γ′ precipitate in a Ni-12.5 at.% A1 alloy

An in situ X-ray diffraction study of the precipitation reaction of a supersaturated solid solution single crystal of Ni-12.5 at.% A1 alloy was performed for moderately high temperatures. The diffusion-control coarsening model of Lifshitz and Slyozov is used to interpret the results of measuring the rate constants determined from the growth of the average particle size and volume fraction of the γ′ phase precipitate as derived from the line...
