Abstract
The paper presents initial results of a modified planar flow
casting process with the aim of producing a multilayer composite
material with an AlPb-alloy-based coating. The monotectic AlPb system is
characterized by rapid separation behavior of the components in the
liquid phase. The coarsening of Pb precipitates due to diffusion- and
coagulation-effects is estimated and with regard to the required
microstructure, Al with finely dispersed Pb, the necessary cooling rate
and the temperature gradient perpendicular to the substrate are deduced.
Based upon these assumptions the numerical simulation aided design of
the thermal process is described. Experimental results, achieved on a
pilot plant, are shown and the microstructure of the produced multilayer
composite is discussed.
