Comparative Study of Squeeze Casting of AA6061 with and without Employing Ultrasonic Cavitations

Abstract:

The automotive and aerospace industries have been the main driving force behind the search of new production processes which are capable of producing components with high integrity. Squeeze casting is one such novel metal processing technique which combines the advantages of both casting and forging in one operation. Squeeze casting process is suited for all melting ranges of metals varying from lead to iron. But nowadays, light weight materials like aluminium and magnesium are mostly used in the above mentioned industries. Aluminium alloy 6061 is one such futuristic material that is widely employed to produce automotive and aerospace components. In this research two sets of cylindrical components of AA6061 were produced through squeeze casting where the first set of components was produced without employing ultrasonic cavitations and the second set of components was produced by employing ultrasonic cavitations and the components were tested for tensile strength and hardness respectively. It was observed that the values of tensile strength and hardness exhibited by the components produced using ultrasonic cavitations were higher when compared to the values exhibited by the components produced without employing ultrasonic cavitations.
