| 英文摘要 | The effects of heat treatment on the microstructures and rupture properties at 1070 degrees C/140 MPa of a hot-corrosion resistant single crystal superalloy were investigated. The results show that long-term homogenization heat treatment significantly reduces element segregation. With prolonging the homogenization time, the area fraction of micropores is gradually increased, the average size keeps increasing, and the density of micropores is increased firstly and then decreased. With increasing the primary aging temperature, the size of gamma' phase is enlarged gradually, and the area fraction of gamma' phase is firstly increased and then decreased. The stress rupture life of the alloy is increased firstly and then decreased with increasing the primary aging temperature. When the primary aging temperature is 1100 degrees C, the size of the cubic gamma' phase is about 370 nm, the squareness is better, the area fraction of the gamma' phase is the largest, and the stress rupture life is the longest. The stress rupture fracture is characterized by ductile fracture. The carbides and micropores at the sub-grain boundary are the main crack sources to cause the stress rupture fracture of the sample. |
