| 英文摘要 | Quasi in-situ observation indicates that the basal slips, prismatic slips and pyramidal a slips are main slip types in & alpha; grains, and twinning tends to occur in & alpha; grains with c-axis nearly parallel to the applied stress for additively manufactured Ti-6Al-4V alloy in low cycle fatigue regime. The slip induces dense dislocation of cells or walls, and the deformation twinning leads to subgrains with higher misorientation. Nanograins with low-angle grain boundaries (2 degrees -10 degrees) and {1012} twins are also found in very high cycle regime. The slip and deformation twinning are both contributors to the nanograin formation during fatigue loadings. |
