Abstract : An experimental determination of the yield locus for a 3/16-in.-thick sheet of a 4 Al-1/14 O2 alpha-titanium alloy was made. The amount of texture hardening in this alloy is large. Yieldlocus diagrams are presented for 0.2% strain. The innter curve is predicted according to the Mises yield condition for an isotropic material. The duter curve was calculated from anisotropic plasticity theory using the yield strengths and plastic strain ratios from unidirectional tensile tests in rolling and transverse directions. Experimental points for combined-stress loading were obtained from through-thickness compression and planestrain tests (both tension and compression). (Author)
