| Abstract | The high-temperature stress rupture properties of K417G superalloy with various Mn contents (0.09wt%similar to 0.35wt%) were studied and the existence form and distribution of Mn were evaluated as well. The results show that Mn is solid-dissolved in gamma matrix and enriched in gamma'-depleted matrix in front of gamma+gamma' eutectic cap. Mn elements promote the segregation of Al and Ti to interdendrite zone, thus increasing the volume fraction of gamma+gamma' eutectic in interdendrite zone and decreasing the size of gamma' phase in dendrite core. With the increase of Mn content, the stress rupture life and the plasticity decrease greatly under the condition of 950 degrees C/235 MPa. The alloy with the minimal Mn content shows the optimal high-temperature stress rupture properties. |
