In the present study, a basic comparison between the cold formability of a commercially-pure Titanium (CP Ti) sheet in the single-point incremental forming (SPIF) and stamping processes is presented. An attempt was made to evaluate the SPIF formability by employing two tests. In the first test, parts having continuously varying wall angles were formed. While in the second test, parts having fixed wall angles were formed. The stamping formability was determined by conducting the limiting dome height (LDH) test. It is concluded that the forming limit curve (FLC) in SPIF is located much higher than the stamping FLC, even higher than the fracture limit curve in stamping. Moreover, the SPIF formability shows dependence on the test employed.

EBSD investigation of texture and microstructure evolution during a complete thermomechanical treatment of commercially pure titanium (HCP-Ti) is presented. Titanium was cold rolled to reach various degrees of thickness reduction: 20%, 40% and 60%. Next, annealing in air atmosphere was conducted at different conditions to achieve the recrystallized state. EBSD topological maps were measured on RD-TD and RD-ND surface of each sample. Strong heterogeneity of deformed titanium microstructures is described with focus on the important role of twinning mechanisms. Texture evolution in investigated titanium appears to be limited, especially in recrystallized state. However some subtle mechanisms are discussed.
