摘要
提出了一种镁合金无缝管穿孔新方法(二辊斜轧穿孔),并利用三维有限元分析软件DEFORM-3D对二辊斜轧穿孔过程进行了模拟,分析了穿孔过程中的微观组织演变。结果表明,模拟的微观结构与实验的微观结构具有相同的演变规律,平均晶粒尺寸接近,证明了采用二辊穿孔新工艺穿制AZ31大口径镁合金无缝管的可行性和DEFORM-3D软件模拟结果的可靠性。
A new piercing method(two-high rotary piercing) for magnesium alloy seamless pipes was proposed,and the two-high piercing process was simulated by DEFORM-3D finite element analysis software.Results show that the simulated microstructures and the experiment ones all exhibit the similar evolution rules,and their average grain sizes are close to each other’s,suggesting that the two-high piercing process is a feasible method to pierce AZ31 magnesium alloy seamless tubes and the DEFORM-3D software is a reliable tool to simulate the two-high piercing process.
