Finite Element Analysis of AZ91 Magnesium Alloy During Equal Channel Angular Pressing Process
The equal channel angular pressing 3D model of AZ91 magnesium alloy was set up.Effects of the temperature and friction factors on the effective strain and load-stroke were simulated using DEFORM-3D finite element analysis software.The results show that the deformation zone is mainly located around the cross area of the two channels.With temperature increasing,the maximum value of load-stroke during ECAP process decreases.The higher the friction factor,the larger the gradient of the effective strain,the lower the homogeneity of plastic deformation.
