Abstract

To investigate the evolution of bimetallic composite structure of immiscible alloy, a macroscopic core-shell type structure of 24Cu-16Sn-60Bi alloy was fabricated which consisted of (Cu3Sn, Cu10Sn3) central core and Bi periphery. Ce addition was found to be capable of enhancing remarkably Marangoni motion of secondary droplets in liquid matrix. The role of Ce addition was attributed to change interfacial tension of droplet/matrix. The results show the possibility of modulating core-shell type structure in immiscible materials by doping rare earth elements.
