| Abstract: | The microstructural evolution nearby-liquidus semi-continuous casting ZL201 aluminum alloy during remelting was studied by means of electron microscope and image analyzer. The results showed that a thixotropic microstructure liable to form semi-solid metal is obtained when the alloy is remelted at 620°C - 630°C then held for 5 min - 10 min. Under such conditions, the average equal-area-circle grain diameter is 43.8 μm with average roundness 1.87. An ideal semi-solid or paste-like ZL201 Al-alloy is thus obtained through nearby liquidus semi-continuous casting. |
