In a precipitation hardening alloy, coring usually results in the precipitation of an eutectic between the dendrite arms. With regard to aluminum?copper alloys, Singh and Flemmings have assumed that this eutectic is divoriced (consists only of the ? phase), and have derived an equation to describe the kinetics of homogenization that is similar to that discussed in the text for homogenization of a cored solid solution alloy. This equation which applies to a solution treatment close to the solvus is:
