摘要：
The tensile properties of DD6 alloy with twist low angle boundaries were investigated at 760 degrees C, 850 degrees C and 980 degrees C, and the misorientation angle of twist low angle boundaries of the specimens of the alloy varies from 0 degrees to 12 degrees. The results showed that when the angle of low angle boundaries is relatively small, it has a little effect on the tensile properties of the alloy. It is notable that effects of low angle boundaries on the tensile strength are weaker than those on the tensile elongation. The characteristic of quasi-cleavage, intergranular and dimple fracture were observed on the tensile rupture surfaces of the specimens, and the tensile fracture mechanism was discussed.
