The effect of heat treatment on the anisotropic mechanical properties of metastable β titanium alloy is investigated in this work. The anisotropic deformation behaviour is mainly due to the formation of band-like macrozone and texture during forging, which can be effectively weakened by solution + aging treatment. Both the microstructure and texture of the heat treated samples are favourable for the lower strength, higher ductility and impact toughness of axis direction (AD) samples than circumferential direction (CD) ones. Besides, the CD impact samples have stronger anisotropy than AD samples. The delamination along different directions happens in the impact fracture surface of CD samples.
