This paper studied the effect of wall thickness and specimen diameter on the mechanical property of TA6V castings. Grain size on the cross section of test pieces after testing was analyzed by optical metallography and fractography was observed by scanning electron microscopy. The results show that grain size grown up with the increasing thickness, meanwhile tensile strength and yield strength improved with the increasing thickness and specimen diameter. The diameter selection of tensile specimen should depend on the castings grain size. The crack initiates at the center of specimen and the fracture mechanism is brittle transcrystalline rupture.
