摘要: Abstract Three deformation routes for recently invented severe plastic (SPD) method named tube channel pressing (TCP) have been introduced in this paper. The effects of routes, back pressure and friction investigated on behavior commercially pure (CP) aluminum tubes. Utilizing finite element analysis provides a broader understanding these through different routes. Due to the large values strains accumulated TCP, modified Estrin–Toth–Molinari–Brechet (METMB) constitutive model has employed program consider realistic flow stress material TCP. Employing experimental procedures confirms accuracy analysis.
