Effect of temperature and rolling direction on the formability of CP2 and Ti-6Al-4V titanium materials

Abstract Pure (CP2) and alloyed titanium (Ti-6Al-4V) have an important place in biomedical and aerospace applications due to their low density and high strength properties. In this study, the effect of the formability of CP2 and Ti-6Al-4V titanium alloy at different temperatures on mechanical properties and microstructure was investigated. The hot forming process was carried out by pressing 1 mm sheet titanium plates at different temperatures on the U profile mold. Specimens along the rolling direction and perpendicular to the rolling direction were taken from the bottom the formed U-plates. Afterward, tensile tests, microhardness measurements, and changes in microstructure were examined, respectively. As a result, at high temperatures and in different rolling directions, significant changes in microstructure and mechanical properties were observed. It was determined that the best forming temperature of CP2 and Ti-6Al-4V materials along the rolling direction was 500 °C, white it is 400° for perpendicular to the rolling direction was 400 °C.
