| 英文摘要 | In the present work, the anisotropic creep ageing behaviour and microstructural evolution of 2195-T84 Al-Li alloy are investigated under different tensile stresses. It is found that the anisotropic creep behaviour of 2195-T84 Al-Li alloy changes significantly with the increase of the applied stress. Microstructural observations confirmed that the movable non-octahedral slip systems increases with the applied stress. The obtained results show that with the increase of the applied stress, the dislocation density in the alloy increases obviously, and the 0' phase coarsens significantly in the late stage of creep ageing process. In addition, there is obvious dislocation slip band in the precipitation free zone (PFZ) with high stress level. The non-octahedral slip and grain boundary slip under high stress level change the dislocation mobility of different orientations, which is the main reasons for the change of the creep anisotropy of the alloy. The results revealed a new mechanism accountable for the distinctly anisotropic creep ageing behaviour. |
