ABSTRACT
Different cold rolling and recrystallization annealing of commercially pure titanium (CP-Ti) sheet was conducted. Microstructural evolution in commercially pure titanium sheet after cold forming and recrystallization annealing were investigated. Cold forming properties using a microstructural analysis, Vickers microhardness and erichsen value measurements were performed. Alpha grain sizes of processing 1 and 2 are 38.67μm and 40.12μm, respectively. Erichsen values of the specimens of processing 2 reaches the high value. This is attributed to recrystallization annealing. Equiaxed alpha grains are formed from the elongated grains and cold forming properties of CP-Ti were improved. The effect of the first recrystallization annealing was remained. Forming properties were a moderate value for processing 1 due to the presence of equiaxed grains.
