| 英文摘要 | Discontinuous plastic flow due to dynamic strain aging (DSA) in a Fe-Ni-based superalloy was investigated by tensile tests in the temperature range from 500 degrees C to 800 degrees C with different gamma ' fraction. Type A serrations were observed in the solutionized and as-aged specimens at 500 degrees C, which was a result of diffusion of carbon atoms. The stress amplitude was affected by the dislocation density induced by the presence of gamma ' phase. Type C serrations occurred in the solutionized and under-aged samples at 650 degrees C and 700 degrees C. With the increase of gamma ' phase fraction in the initial microstructure, the stress amplitude and duration of type C serrations decreased at 700 degrees C. It was demonstrated that the dominant deformation mechanisms of under-aged specimens at 650 degrees C and 700 degrees C were weakly-coupled dislocation pairs shearing the fine gamma ' particles with slip bands, while the deformation mechanism transformed to dislocation climbing at 800 degrees C. The model linking serration amplitude, solute concentration at the dislocation line and dislocation density was used to analyze the effect of gamma ' dynamic precipitation on the DSA. The dynamic precipitation of gamma ' phase during tensile significantly alters the DSA behavior by removing substitutional solutes responsible for gamma ' precipitation from the matrix. |
