The constitutive equation of the alloy was established according to the thermal simulation compression tests of semi-solid billet of ZL201 alloy prepared by a near-liquids semi-continuous casting method.Parameters of power law model

such as apparent viscosity

were presented based on the constitutive equation of semi-solid ZL201 alloy and the Stefan equations.The software Anycasting was applied to simulate and analyze the semi-solid die-casting processes of semi-solid ZL201 alloy.The effects of the ingate size on semi-solid die-casting process of the alloy were investigated

and potential defects in the die casting components were predicted.The results show that the desirable filling process of semi-solid metal slurry can be realized with ingate thickness of 3mm.
