Porosity in Disk Shape Spray Formed Al-Si-Pb Alloy Preform

Aruna Tomar and Devendra Singh

Spray forming technique was employed to produce a disc shape preform of Al-Si-Pb alloys. Porosity of this disc was investigated as a function of lead content and the distance from centre to periphery of the disc. The porosity decreases with distance from centre to periphery for all compositions of lead. The decay rate in porosity increases with the increase in lead content. Also the decay rate in porosity decreases towards the periphery of the deposit. The areas having large and small amount of porosity were observed in the microstructure of Al-Si-Pb alloys. The large and small amount porosity areas belong to the lead and aluminum rich areas, respectively.
