Abstract

In this paper friction assisted tube forming (FATF) and friction assisted tube extrusion (FATE) are proposed to deform cylindrical tubes for desirable radius and thickness. These methods were successfully examined on commercially pure copper tubes. Finite element analyses were executed to simulate heat generation, temperature and strain fields. Using friction power in the presented methods not only significantly reduced processing force but it also enhanced imposed strains. Mechanical properties of the processed tubes showed considerable changes in which yield strength and ultimate tensile strength increased 4.6 and1.6 times greater than those from the initial values. Dynamically recrystallized fine grains with mean size of 8.3µm were obtained compared with 60µm for the annealed sample.
