摘　　要：镁合金是最轻的工程金属材料,在新能源汽车、航空航天等领域具有广阔的应用前景,而在这些领域中广泛存在弯曲变形。但镁合金弹性模量较低,室温弯曲成形回弹量大且不易控制,严重影响构件成形精度和后期服役性能,精确预测和控制镁合金回弹仍是目前亟待解决的重要问题。近年来,为了提高镁合金的成形精度,并扩大其工业化应用,各国学者针对镁合金板材弯曲回弹预测及控制方法进行了大量研究。本文综述了镁板弯曲回弹预测与控制的最新研究进展,介绍了常见的镁合金回弹预测手段,对比分析了镁合金回弹的影响因素与控制方法,最后对镁板弯曲回弹未来研究重点进行了展望。Magnesium(Mg)alloy is the lightest engineering metal and has broad application prospects in new energy vehicles,aerospace fields,etc.,where bending deformation is widespread.However,due to the low elastic modulus,the springback of Mg alloy is large and not easy to control when bending at room temperature,which seriously affects the forming precision and post service performance of parts.So,accurate prediction and control of springback for Mg alloys is still an important problem to be solved at present.In recent years,in order to improve the forming precision of Mg alloy and expand its industrial application,scholars in various countries have proposed many methods for predicting and controlling the springback of Mg alloys.In this paper,the research progress on the prediction and control of springback during bending of Mg alloy is reviewed,several common methods in predicting the springback are introduced,and the influencing factors and control methods of springback are analyzed.Finally,future research directions on this field were proposed.
