Abstract
The Magnetic moulding process is an extension of lost foam process, in which an Expendable Poly Styrene (EPS) pattern is surrounded by steel shots bonded together by the action of an induced electromagnetic field. Magnetic moulding is a potential alternative for conventional sand casting, which has disadvantages like low thermal conductivity and low permeability, which affects the metallurgical and mechanical properties of the casting. In the present work Al/SiCp metal matrix composite (MMC) samples are moulded by magnetic moulding technique, using different size steel shots viz. 0.18 mm, 0.6mm, 1mm and the tensile properties of the moulded samples were evaluated. The fractured surfaces of the tensile samples were also examined using SEM. The results show that medium size steel shots gives better tensile properties.
