Abstract: To make sure of the effect of anisotropy on the shape/size precision of workpiece, a series of hole-flanging experiments were carried out at room temperature and 600°C, with 1.5 mm-thick TC2M titanium alloy sheet as specimens on which pre-drilled holes were provided at the center. It was found that there are some nonaxisymmetric distortions such as peripheral flange warpage, elliptical opening shape, uneven lip surface of the finished hole and ununiformly distributed wall thickness after unloading in addition to the normal rupture at lip edge when the initial hole diameter is smaller than the minimum size. The flanging process at high temperature can improve effectively formability, get rid of peripheral warpage and elliptical opening, but the lip surface and wall thickness can not be evened yet. The ultimate hole-flanging coefficient is given in two different states, while the nonaxisymmetric distortions are quantitatively described and analyzed.
