Effect of Friction Coefficient on Hot Rolled Rings of AZ31 Magnesium Alloy
A 3D elastic-plastic and coupled thermo-mechanical FE model of hot radial-axial rolling of AZ31 magnesium alloy was established based on the ABAQUS/Explicit platform. The influences of friction coefficient on the non-uniform distribution of strain and temperature, along with rolling force and power parameters were analyzed. The results show that the strain distribution of the rolled ring becomes more homogeneous, and the temperature distribution, rolling force and rolling torque do not change significantly with the increase of friction coefficient.
