| 英文摘要 | Deformation and yield induced structure transitions of polyamide 6 (PA6) were detected with the combination of the wide- and small-angle X-ray scattering (WAXS and SAXS) at 30 degrees C below glass transition temperature (T-g) of PA6. During deformation, gamma-alpha phase transition was found at elastic stage. The concentrated stress in crystals at elastic stage provided adequate energy for the direct gamma-alpha phase transition under T-g. The force to promote the gamma-phase into a phase directly is insufficient at the yield stage and a transient phase as a compromise was formed. The transient phase was confirmed by DSC measurements and assisted the gamma-alpha phase transition indirectly. The gamma-phase slips into incomplete fragments at yield point, and the parts along tensile direction are responsible for the formation of transient phase. The gamma-fragments after yield is oriented by shear force following alpha-phase. The yield of PA6 was intimately related with the gamma-transient phase transition and the slippage of gamma-fragments. In addition, the increase of long spacing at elastic deformation along tensile direction was mainly contributed by the amorphous region. After yield, the phase transition and crystalline slippage affected the lamellar evolution. A simplified schematic diagram was provided to illustrate the structure evolution of PA6.
