Abstract:A new kind of compound extrusion technology including direct extrusion and shears for AZ31 magnesium billets can cause plastic large deformations and high strain rates. A series of compressive tests have been done to obtain the stress-strain curves of AZ31 magnesium alloy. Three-dimensional (3D) thermo-mechanical coupled finite element modeling of forming magnesium alloy AZ31billets into small rods at certain high ram speed and low temperature by extrusion-shears have been carried out. The simulation model has… Show more

“…The additional tensile stress increases with the development of ES process, and when it reached the fracture limit, the cracks would appear on the surface of rod. The best way to avoid the surface cracks is to decrease the axial additional stress 15 . …”
