| 英文摘要 | The influence of service-induced degradation on residual life is very important for the safe service of turbine blades. In this study, a series of simulation experiments were conducted on a directionally solidified superalloy under (880-1020) & DEG;C/(70-220) MPa and interrupted after 500 h. Then, the stress rupture life of the interrupted specimens was tested under 980 & DEG;C/275 MPa. The results showed that the increase of simulated experiment temperature decreased the residual stress rupture life. In brief, the simulation experiments at 880 & DEG;C did not influence the residual stress rupture life of the alloy. The simulated experiments at 980 & DEG;C and 1050 & DEG;C mainly affected the microstructure of gamma' phase, while not gamma/gamma' eutectic and carbides. After the stress rupture tests under 980 & DEG;C/275 MPa, cracks were located at the interfaces between carbides and gamma matrix in the interdendritic regions. This study provides guidance on the degradation evaluation and safety service of the directionally solidified superalloys. |
