In the present work, the microstructural features of spray deposited Al-6Si-10Pb alloys before and after annealing at different locations of the preform have been compared with each other. XRD confirms the presence of all elements present in the Al-6Si-10Pb alloy.  The optical micrographs were taken at three different regions of the preform before and after annealing predicts that the grain size is lower at the peripheral region as compared to central region. Equiaxed grain structure was observed in SEM images, with a uniform distribution of Pb and Si phase in an Al-matrix. Further, grain refinement and reduction of porosity was observed after annealing.
