| 英文摘要 | The solution-treated second-generation single crystal (SX) superalloys underwent hot isostatic pressing (HIP) at 1316 degree celsius and 105 MPa for varying durations. This study investigates the effect of HIP on micropores and stressrupture behavior under conditions of 980 degrees C and 250 MPa. The results illustrate that the application of HIP treatment significantly reduces the porosity and volume of micropores, thereby increasing the rupture life of the alloys. With the disappearance of micropores, the crack initiation site shifts from the micropores to the gamma/gamma' interface, resulting in reduced crack dimensions and decelerated propagation. Consequently, the smaller size of cracks in HIPed specimens slow down fracture. Nonetheless, the crack propagation pattern remains consistent: cracks expand perpendicular to the stress axis, connecting with cracks at other heights via secondary cracks along the <112> direction. |
