Experimental Research And Numerical Simulation Of Bulging For AZ31 Magnesium Alloy Tube With Elastic Internal Die

The machining technology of forging tube is making use of circular tube blank and gains tubular components. It is an innovative technique. The machining technology of forging tube makes the forging parts mass light, intension high, cost little and machining exactness. So it is the important aspect in 21 century in the forging and machining fields.Today the application of AZ31 magnesium alloy has been extensive recognized for people. If the magnesium alloy tube can be machining through some given technologies such as bulging and tube sinking for magnesium tube material, there is a high added value for the product. But the magnesium alloy has a bad plastic property on room temperature, it is difficult to meet the needs of post forming process. Especially the production technology of AZ31 magnesium alloy is the tube can be welding with flux, so the tube has some weld bead. The dates of mechanical property and forming limit of AZ31...
