摘要 镁合金在常温下的塑性成形能力差,在加热条件下成形能力会有明显提高。文章研究了AZ31B板材在温热条件下的成形性能。通过完成刚模胀形实验获得了AZ31B在温度150℃、200℃、250℃的FLD。AZ31B镁合金板材FLD随着温度的升高而升高,表明AZ31B随着温度的升高塑性成形能力增强。在实验基础上进一步获得了成形极限图的计算模型,该模型对实际生产有一定的指导作用。 Due to AZ31B's low formability at room temperature,the FLD experiments were employed at 150℃,200℃,250℃.The FLDs show that the formability of AZ31B sheet increases with increasing temperature.The FLD calculating model established based on experiment data can be guidance for the practical production.
