    Abstract:

    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.
