| 英文摘要 | The beta-NiAl phase, which may exacerbate the high-temperature mechanical properties of Ni-based superalloy, was observed in a designed Re-containing single crystal superalloy. The solidification mechanism of beta-NiAl phase and its evolution after solution treatment as well as long-term aging at 1120 degrees C were systematically investigated. The beta-NiAl phase was confirmed by the analyses of XRD and TEM in as-cast specimen. Combined the analyses of TEM, DSC, phase diagrams and chemical segregation behaviors obtained via EPMA, the solidification path in interdendritic region was determined as L -> (beta-NiAl+Cr) eutectie, L -> beta + delta, L +beta ->gamma', L -> gamma'. The beta-NiAl phase could be diminished by solution treatment and/ or long-term aging treatment. After the solution treatment at 1330 degrees C for 30 min, the p-NiAl phase split into small bulks and the delta phase dissolved, contributing to the formation of the gamma + gamma' structure and large blocky delta phase. During the long-term aging at the 1120 degrees C, the beta-NiAl phase transformed into gamma and gamma' phase. With aging time prolonging, the Cr-rich phase dissolved, which promoted the precipitation of TCP confirmed as mu phase with three morphologies. |
