摘要：

The morphology and growth kinetics of the cellular precipitate and discontinuously coarsened cellular precipitate have been studied in the temperature range 573-731 K. The alloy decomposed by cellular precipitation into a lamellar structure consisting of alternate lamellae of the alpha and PARTIAL phases all aging temperatures. The fine lamellar structure of the primary cells decomposed into a coarse lamellar structure by a discontinuous coarsening or secondary reaction. Analysis of growth kinetics indicates that the transformations are controlled by diffusion through the cell boundaries.
