Abstract

The growth and congregation of minor phase in immiscible Cu-Fe alloys were investigated. Results showed that the Brown motion was strongly affected by the initial number of the separated droplets. With the increase of initial numbers of droplets, the time needed for completing the Brown congregation reduced. The calculation confirmed that increasing the radiuses of droplets would lead to the decrease of the time for congregation completed. As the increases of the undercooling and the droplet radius, the ratio of Stokes motion velocity to Marangoni motion velocity increased.
