Abstract

Laser alloyed tracks were produced by blowing aluminum powder into melt pools generated in zinc substrates. Analysis of the microstructures revealed a structural and compositional stratification related with a deficient aluminum redistribution in the liquid. The effect of chemical heterogeneity on solidification mechanisms was modeled. The composition gradients and the solidification undercooling were shown to strongly influence the geometry of the solidification front. A reasonable agreement was obtained between experimental and predicted characteristic dimensions of the microstructures, in particular, the radii of the dendrite tips observed experimentally were comparable to the calculated ones.
