用透射电子显微镜和小角X射线散射研究了高耐热聚(丙烯腈-丁二烯-苯乙烯)(ABS)的变形机理。本工作是在我们先前研究的基础上进行的，其中用电子显微镜观察银纹，用SAXS观察剪切屈服，以评价ABS在静态拉伸和Izod冲击下的力学性能与变形机制之间的关系。目前的结果支持了我们先前的结论，即透射电子显微镜和小角X射线散射的结合使我们能够识别ABS的变形机制，并为银纹化和剪切屈服共存提供了新的证据。SAXS图谱表明，即使在冲击载荷下，ABS也发生了剪切屈服。研究表明，剪切屈服的发生对ABS的增韧效果有重要影响。©2002威利期刊，Inc.应用多维科学杂志85：17-24,2002
Deformation mechanisms in a high thermal resistant poly(acrylonitrile-butadiene-styrene) (ABS) were investigated using transmission electron microscopy (TEM) and small-angle X-ray scattering (SAXS). The work followed our previous study, in which TEM was used for the craze observation and SAXS for the shear yielding, to evaluate the relationship between the mechanical properties and the deformation mechanisms of the ABS under static tension and Izod impact. The current results support our previous conclusion that the combination of TEM and SAXS enables us to identify the deformation mechanisms in the ABS, and provide new evidence for the coexistence of crazing and shear yielding. The SAXS patterns suggest that shear yielding occurred in the ABS, even under the impact loading. We concluded from the study that the occurrence of shear yielding had a major effect on the toughness enhancement of the ABS. © 2002 Wiley Periodicals, Inc. J Appl Polym Sci 85: 17–24, 2002
