采用相变介质冷却铜模快速冷却技术,通过熔体凝固制备铸造铝合金A356。用这种技术实现的冷却速率在102 K/s的量级。制备了直径为10 mm的铸态试样。研究了该合金的显微组织和力学性能。结果表明,与传统铸造方法相比,采用该技术可以更好地细化一次和二次枝晶臂间距(DAS)。通过改变冷却介质的量,可以在一定程度上控制冷却速率。随着冷却速度的增加,DAS减小,显微硬度和强度相应增加。
A fast-cooling technology using a copper mould cooled by a phase-transition medium was used to prepare cast aluminium-A356 alloy by solidification of the melt. The cooling rate achieved with this technique is in the order of 102K/s. As-cast samples with a diameter of 10mm were produced. The microstructure and mechanical properties of this alloy have been investigated. The results show that both the primary and secondary dendrite arm spacing (DAS) are better refined by using this technology than with a conventional casting method. The cooling rate can be controlled to some extent by changing the amount of cooling medium. The DAS decreases with increasing cooling rate, and the microhardness and strength increase correspondingly.
