γ-TiAl alloys have attracted interest as lightweight materials for structural applications at temperatures below 800 o C. With recent improvements in microstrutural control of the γ-TiAl alloys, resulting in excellent creep properties and high temperature strength, their use can be extended to temperatures higher than 800 o C. To increase..... More
