A more complex structural component with small size and very thin walls and blades used for advanced aircraft engine was fabricated well by induction skull melting and centrifugal investment casting with a proper ceramic mold. The tensile elongation and ultimate strength of the hot isostatically pressed (HIPped) Ti 46.5Al 2.5V 1Cr (mole fraction, %) casting alloys are up to 2.5% and 645?MPa at room temperature, and 31% and 593?MPa at 800?℃. The fracture roughness at room temperature is up to 28?MPa·m 1/2 . The endurance tensile strength at 800?℃ for 150?h, is higher than 200?MPa. The high cycle rotary bending fatigue strengths for 1×10 7 cycles at room temperature and 800?℃ are 412?MPa and 270?MPa, respectively.
