- Abstract
- Plastic deformation behavior in T-shaped equal channel pressing, a modified equal channel angular pressing (ECAP) using T-shaped channel instead of conventional L-shaped channel, is analyzed by using the commercial finite element code DEFORM. Simulations were carried out under realistic conditions by considering the strain hardening of material and friction. The deformation behavior is more complicated and the strain induced is highly localized. Severe plastic strain is localized in the bottom region of the workpiece and very small strain is developed in the other region, which is in good agreement with the experimental results reported in the literature showing the nonuniformity in microstructure and hardness distribution. In addition, the load requirements of the T-ECAP are much higher compared to conventional ECAP.
