具有宽凝固范围的铸造合金易于发生热裂。本文研究了用计算机模拟预测热裂位置和强度的方法。在不同浇注温度下对A206铝合金进行了模拟。随着α的增加，临界分数凝固时间增加，这意味着合金更容易发生热裂。这些理论预测与实验结果完全一致。
Cast alloys with wide solidification ranges are prone to hot tearing. This study deals with prediction of hot tearing location and its intensity by computer simulation. The simulation was performed at different pouring temperatures on A206 aluminum alloy. As superheat increases, the critical fraction solid time increases which means the alloy is more susceptible to hot tearing. These theoretical predictions are in complete accordance with experimental results.
