| 英文摘要 | The under-aging, peak-aging, and over-aging microstructures of a precipitation-strengthened Fe-Ni-based alloy were designed by applying different heat treatment procedures. Tensile creep tests were conducted at 700 degrees C and 250 MPa on samples exhibiting different strengthening gamma ' precipitate volume fractions and diameters. The creep life of the alloy in the under-aged state was increased by more than 10% compared to the peak-aged condition, which provided a new approach to designing the heat treatment regime that improve the creep rupture life and plasticity of precipitation-strengthened alloys. The improvement in creep properties of the under-aged state was attributed to the transition from shearing to Orowan looping of gamma ' particles by matrix dislocations during the dynamic precipitation and coarsening of gamma ' phase, increasing intragranular deformation resistance. The underaged microstructure design allowed reducing the grain boundary sliding contribution to overall strain during creep. As a result, the steady-state creep stage of the alloy in the under-aged state was extended. Additionally, relationships between applied stress and nucleation, growth, and coarsening of the gamma ' phase have been evidenced. |
