SOLUTION KINETICS OF CuAl2 IN AN Al-4Cu ALLOY.

Abstract

The results of a recently-developed, spherical, finite geometry, mathematical model using numerical methods are compared to existing closed-form models. The geometry and boundary conditions imposed by the closed-form models are shown to be restrictive in the application of these models to the solution kinetics of second phases. A quantitative metallography study of the solution kinetics of CuAl2 in an Al-4w/o Cu alloy was undertaken to provide data on the changes in second-phase particle size distributions as a function of solution treatment time. The size distributions were shown to vary according to the proposed spherical, finite model formulated using numerical methods. (Author)
