Microstructures of melt spun hypomonotectic Al-7wt%In, hypermonotectic Al-5wt%Pb and near monotectic Al-2wt%Pb alloys have been examined by transmission electron microscopy and consist of 10-150 nm diameter faceted In particles and 5-150 nm faceted Pb particles homogeneously distributed in an Al matrix. As-melt spun In and Pb particles exhibit bear cube-cube and cube-cube orientation relationships with the Al matrix respectively, and truncated octahedral shapes bounded by [111] and [100] facets. In this paper the melting behavior of In and Pb particles in as-melt spun Al-7wt%In, Al-5wt%Pb and Al-2wt%Pb alloys is investigated by heating and cooling experiments in a differential scanning calorimeter and in situ heating experiments in a transmission electron microscope.
