abstract = "Composition profiles of the eutectic alloy Bi43Sn57 atomic % grown
by normal and inverted vertical Bridgman methods are presented and
the study of the solute alloy redistribution is made. The inverted
vertical Bridgman method (IVB), where the solidification occurs
from the top to the bottom of the melt under a destabilizing
thermal gradient, allows the growth of crystals with
buoyancy-driven convection different from that of the usual
vertical Bridgman (VB) configuration. The scope of this work is to
study the influence of the gravity in the convection process. The
convection is smaller in samples solidified by VB, with more
stable solute and density distribution profiles. In both methods
the samples presented dendritic structures plus irregular eutectic
structure along its length.",
