| 英文摘要 | The effects of Ce on the precipitation behaviors and creep properties in 316LN austenitic stainless steel (316LN) were studied by experiments and first-principles calculations. It was found that Ce in 316LN induces intragranular Laves phase precipitates with an average diameter of 166 nm. Aside from Ce rich in TiN nanoparticles facilitating Laves phase precipitation by heterogeneous nucleation, the solute Ce atom attracting its surrounding Mo atoms favors Laves phase precipitation by homogeneous nucleation. These intragranular Laves phases strongly impede the dislocation climbing and thus enhance the creep resistance. Here, 0.032 wt% Ce addition in 316LN considerably extends the creep life from 313 h to 556 h at 700 degrees C/150 MPa. These results provide a new insight into profoundly understanding the microalloying mechanism and effects of rare earth elements in heatresistant steels. |
