摘要： <正> The effect of strain rate on the bend ductility and notch fracture toughness of Ti-24Al-11 Nb wasstudied,it was found that the strain rate with a range of 1.17×10~(-5)～1.17 ×10~(-3) at 20℃had nega-tive influence on both properties based on different microstructures.

Abstract: The effect of strain rate on the bend ductility and notch fracture toughness of Ti-24Al-11 Nb was studied,it was found that the strain rate with a range of 1.17×10~(-5)～1.17 ×10~(-3) at 20℃ had nega- tive influence on both properties based on different microstructures.

Key words: bend ductility, notch fracture toughness, strain rate
