| 英文摘要 | Recent research on the mechanical properties of additively manufactured (AM) superalloys is mostly focused on their tensile behavior at room temperature. Three carbon content (0.05 wt%, 0.1 wt%, 0.15 wt%) were selected to explore their effect on the tensile properties of a specific AM superalloy tested at temperatures up to 760 degrees C and 1000 degrees C. Thermodynamic calculations were carried out together with scanning electron microscopy (SEM), transmission electron microscopy (TEM), and electron backscatter diffraction (EBSD) techniques. With the gradual increase in carbon content, tensile strength of superalloys at 760 degrees C is enhanced through precipitation strengthening of carbides and improved interfacial strength including both grain boundaries (GB) and gamma/gamma ' phase interfaces. Additionally, carbon affects the stacking fault energy, whereby the strength of alloy can be enhanced through lowering stacking fault energy. Conversely, exposure to 1000 degrees C leads to the degradation of primary MC carbides, accompanied by stress-induced recrystallization at the carbide/matrix interfaces. These trigger the matrix softening near carbides and ultimately lead to the strength reduction. |
