. The die casting process involves the injection of liquid aluminum into a die cavity under high pressures. The metal stream "sprays" into the die cavity, causing metal reaction and air entrapment inside..., and heat treated because of these defects[1-4]. To improve the quality and properties of the die casting process, semi-solid metal technique has been introduced. A lot of semi-solid die casting studies......
