Abstract

Centrifugal force is one of the main process variable to control the solidification process in centrifugal casting. This force is controlled by varying rotational speed. The grain size and mechanical properties of the cast varies with mold rotational speed. In this work Al-2%Si alloy is cast under different rotational speed. The grain size is large at lower speed and decreases with increase in mold rotational speed. The hardness of the material increases with increase in mold rotational speed.
