Abstract

The δ phase of nickel-based superalloys plays an important role in mechanical properties and fracture behavior. The tensile tests were conducted to reveal the fracture mechanism of the δ phase. The present study established a fracture model of the δ phase. The fracture of the δ phase occurs more easily when its long axis is closer to the loading axis. Compared to the needle-shaped δ phase, the granular δ phase is more difficult to fracture.
