Abstract : The transition from plane to cellular interface in ternary tin alloys containing lead + antimony was determined experimentally. The transition between the planar and the non-planar interface can be plotted on a graph of initial concentration vs. the ratio of temperature gradient to rate of solidification, in a manner analogous to that describing the plane to cell transition in binary alloys. The observed results indicate an interaction between the lead and the antimony atoms in the alloy, which can be interpreted by assuming that the equilibrium distribution coefficient of the lead atoms has decreased as a result of the addition of the antimony atoms.
