Abstract
In the present paper the sedimentation process in binary multiphase Cu-Sn system is presented. The initial samples were produced by GoodFellow, the initial molar fraction was Cu30Sn70 respectively. Thus, the two-phase region was obtained. The two different phenomena occurs during the process. Mainly, the Cu3Sn and Cu6Sn5 phase growth due to the temperature and migration of pure Sn according to the centrifugal force. Both phenomena’s are described by physical equations. The model describing the phase growth based on the Leibnitz rule – the mass conservation law at the moving boundary and the migration of the elements due to the sedimentation is characterized by equation of motion. The results of the presented models are shown.
