| 英文摘要 | DZ125L superalloy with different contents of impurity elements such as O, N, S and P were obtained through ordinary smelting method and purified smelting method. The microstructures of experimental alloy were investigated by optical microscopy and scanning electron microscopy, and the mechanical properties of alloy were also measured. Results show that the contents of 0, N, S and P for DZ125L alloy can be reduced from 0.0010% to 0.0005% by purified smelting method, and the contents of shrinkage and inclusions decrease with the increase of the purity of DZ125L. The yield strength and tensile strength of the alloy prepared by purified smelting method at room temperature, 760, 850 and 980 degrees C are slightly improved, while the stress rupture properties at 760 degrees C/800 MPa, 850 degrees C/560 MPa and 980 degrees C/250 MPa are improved dramatically. The creep properties at 950 degrees C and fatigue properties at 760 degrees C can also be enhanced by purified smelting method. |
