| 中文摘要 | An investigation was carried out to study the effects of gamma' formation and strengthening elements (Al, Ti and Ta) on the microstructure and stress rupture properties of nickel base single crystal super-alloys. The results show that with the increase of gamma' formation and strengthening elements, the percentage of gamma-gamma' eutectic and the misfit degree of gamma/gamma' increases. Detailed microstructural analysis revealed that with the increase of gamma' forming element content, the morphology of gamma' changed from spherical to cubic, then irregular shape; and the size of gamma' increases gradually. Excessive gamma' formation and strengthening elements will lead to the precipitation of p phase during stress rupture tests. The alloy with 5wt.%Al, 1wt.%Ti and 6wt.%Ta has the best stress rupture property. |
