| 摘 要： | 研究了不同拉伸速度下尼龙-6的多次屈服成颈行为，并采用生物显微镜研究了尼龙-6的球晶形貌。结果表明：在拉伸速率低于50m／min的条件下，可观察到尼龙-6明显的多次屈服成颈行为，这应与拉伸条件下球晶演变形成的微纤维的缺陷有关：采用生物显微镜，可观察到尼龙-6球晶中的发射状微纤、球晶形貌和晶界。

Multi-Yielding Behavior in the Tensile Test and the Spherical Crystals Morphology of Nylon-6 |
| |
| Abstract: | The multi-yielding behavior of nylon-6 in the tensile test was researched,and the morphology of the spherical crystals were observed by polarized microscope and optical microscope.The results showed that the multi-yielding phenomenon could be observed obviously when the tensile rate was 50 mm/min below,which might be caused by the weakness in the micro-fibers structure which was evolved from spherical crystals of nylon-6.The micro-fibers, the morphology of the spherical crystals and the crystals boundary co... |
