摘要：

The delta 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 d phase. The present study established a fracture model of the delta phase. The fracture of the delta phase occurs more easily when its long axis is closer to the loading axis. Compared to the needle-shaped delta phase, the granular delta phase is more difficult to fracture.
