dc.description.abstractIn this paper the effects of rollers-billet friction coefficient (RFC) and plug-billet friction coefficient (PFC) during the skew rolling piercing process are investigated. The piercing process has been simulated and the plastic deformation, temperature evolution, and surface twisting of pierced tube analysed. Results show that the plastic deformation of super-martensitic Cr13 stainless steel increases at higher RFC and decreases at higher PFC. The same trend has been observed for material strain rate, which increases with higher RFC but decreases with increasing PFC. In addition, it has been found that friction coefficient does not affect the temperature evolution of the billet. In fact, the material heating during piercing is related to plastic deformation. Comparison of the fracture surfaces of the hot tension test samples at 0.01 s−1 and 10 s−1 confirm this point. The RFC increases the forward material velocity, and PFC decreases the forward material during the skew rolling piercing process. The PFC decreases the material velocity due to the ductile fracture growth obstacle inside the tube. More plastic deformation at higher PFC leads to higher surface twisting. The maximum surface twisting was 68° at RFC = 0.6 and PFC = 0.06, and the minimum surface twisting was 12° at RFC = 0.2 and PFC = 0.15.en
