Numerical and Experimental Investigation of the Effect of Open-Die Hot Deep Drawing Process Parameters on the Formability of Commercially Pure Titanium


Space Transportation Research Institute, Iranian Space Research Center, Tehran, Iran



In the present study, the finite element analysis of the hot deep drawing process of commercially pure (CP) titanium has been performed without the blank holder in order to investigate the influence of temperature (T), die radius (Rd) and blank diameter (D) on the maximum punch force (Fp) and minimum thickness of the blank (t). Tensile tests were first conducted to extract the mechanical properties of CP titanium sheets at various temperatures to simulate the hot deep drawing process. The results of the numerical simulation were used to perform the experimental tests at the optimal condition of the parameters. The experimental results of the process at the optimal condition of the parameters indicated that there is good agreement between the numerical and experimental investigations. The results indicated that the hemisphere of titanium without any wrinkling, tearing, and without any oxidation can be obtained by a blank diameter of 580 mm and forming temperature of 400°C.
