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 of sedimentation at 453K for 1 hour with the angular speed of 35 000 RPM . 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 equa-tions. The model describing the phase growth based on the Leibnitz rule - the mass conserva-tion 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 show.
