Deformation behavior of TC1 titanium alloy sheet under double-sided pressure WANG Zhong-jin(王忠金), SONG Hui(宋 辉),WANG Zhe(王 哲) School of Materials Science and Engineering, Harbin Institute... bulge(VPB) tests of an annealed TC1 titanium alloy sheet were carried out under two different conditions: double-sided pressure bulging and conventional single-sided pressure bulging. The automated......
)Abstract:A new cup-drawing process of BT20 titanium alloy was studied. Tensile tests were carried out at room temperature, and then cup-drawing experiments were carried out with conical female die at high temperatures. The results show that the plasticity of BT20 titanium alloy is bad, σs/σb is big, n is small, so it is not suitable for BT20 titanium alloy which draws at room temperature, even......
