Solidification behaviour of squeeze cast aluminium composites

Abstract.The effect of die temperature on the solidification behaviour of aluminium mixed ceramic cast samples are
studied. The samples are prepared by squeeze casting method. The die temperatures are assigned in this work from 220 -
280°C and the preparation of aluminium in liquid state of temperature is 850°C, respectively. The application of pressureduring this process is 70 MPa. It was observed that the solidification time varies from 29 seconds at 220oC and 37seconds at 280oC. Increasing the die temperature resulted in decreasing the cooling rate. The experimental and theoreticalsolidification time was almost equal and close in their values.
