摘要： 采用电子显微镜及图像分析仪,系统研究了近液相线铸造ZL201合金在二次加热过程中的组织演变·结果表明:ZL201铝合金半固态坯料在620～630℃保温5～10min,能够获得适用于半固态成形的触变组织,此时,晶粒平均等积圆直径为43 8μm,晶粒平均圆度为1 87·近液相线半连续铸造可以获得理想的ZL201合金半固态坯料·

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.
