This paper investigates the role of TiBAl as a refiner on the ductility of the eutectic Al-Si alloy processed by squeeze casting method. Gravity casting and squeeze casting were carried out on an aluminium alloy with 12 wt% silicon with the addition of different amount of of TiBAl refiner. Investigations on mechanical and microstructural characteristics were done on specimens drawn directly from cast components. Although significant improvements were noticed in mechanical properties and microstructural characteristics with the increase of pressure, remarkable increase was not oberved with the addition of grain refiner in the case of squeeze casting.
