| 中文摘要 | The stress rupture properties of a single crystal superalloy in three orientations were tested under 871 degrees C/552MPa and 1010 degrees C/248MPa. The [0 0 1] orientation shows the longest life and good elongation at 871 degrees C, the [111] orientation exhibits the best elongation, while the life and elongation of [0 11] orientation are both poor at this test condition. At 10 10 degrees C, the anisotropy between [001] and [011] orientation is evidently reduced, however the [111] orientation shows the longest life at the same condition. In [0 0 1] orientation, the N type rafts are formed under two test conditions. In [111] orientation, the gamma' keep cuboidal shape under 871 degrees C/552 MPa, while rafts with direction varying with local position are formed under 10 10 degrees C/248 MPa. In [011] orientation, lots of stacking faults appears in gamma' under 871 degrees C/55 2 MPa, while many twins are formed under 1010 degrees C/248 MPa, which are both related to the activation of {111} (112) slip system. The influence of orientation and test condition on the deformation mechanisms and stress rupture properties is discussed. (C) 2007 Elsevier B.V. All rights reserved. |
