Abstract: An Al-Si containing 13% Si is cast in cylinderical, split metallic mould rotating at different speeds about it's verticall axis. Microphotographs of the castings are taken along the radii. Michrohardness profile are determinded across the cross-section and Impact-tests are conducted on samples obtained from the castings produced at different speeds of rotation of the mould. the speed of ratation is seen to have apositive effect on grain fefinement and distribution of the constituent phases, the effect being optimum at an optimum speed. This optimim speed of rotation of the mould is found to have resulted in an optimization of the Hardness and Impact properties of the casting
