| 英文摘要 | Positron annihilation lifetime and coincidence Doppler broadening measurements have been performed for Ti51Al49 alloy with different amounts of Nb. The experimental results indicate that when a low amount of Nb atoms is added into Ti51Al49 alloy, the Nb atoms mainly aggregate at grain boundaries, which increased the free electron density at boundaries and improved the toughness at room temperature of TiAl alloys. In contrast, the densities of free electron at grain boundaries and in bulk decreased for high Nb doped alloy, due to the formation of the new ordering structure, which increases the brittleness of TiAl alloys. |
