An experimental study was carried out on a semi-solid diecasting process using a mixture of elemental alminum and silicon powders. The mixed powder with hypo or hyper eutectic composition was heated to the semi-solid state temperature and then stirred mechanically. After stirring, the powder was forced into the preheated metal die. The fluidity of the stirred hypo eutectic slurry was high and stirring improved the surface quality of the products. The <i>α</i> phase or Si phase particle in the slurry grew globular from collision during the stirring. Eutectic structures were refined by the stirring of the slurry. The tensile strength, elongation and hardness of the products made from the stirred slurry were higher than those of products made from unstirred slurry.
