通过扫描电子背散射衍射图和透射电子衍射图研究了含碳量为0.0026 ~ 0.61%的Fe-C合金板条马氏体的形貌和晶体学。随着碳含量的增加，包和块的尺寸都减小。在低碳钢（0.0026-0.38%C）中，在光学显微镜下观察到具有不同对比度的块包含两组（子块）板条，这两组板条是两种K-S变体，取向偏差约为10度。另一方面，在高碳合金（0.61%C）中，块由单个K-S变体的板条组成。(C) 2003材料学报。Elsevier Science Ltd.出版。版权所有。
The morphology and crystallography of lath martensite in Fe-C alloys containing various carbon contents from 0.0026 to 0.61% were studied by analyzing electron back scattered diffraction patterns in scanning electron microscopy and Kikuchi diffraction patterns in transmission electron microscopy. As carbon content increases, the sizes of both packet and block decrease. In low carbon steels (0.0026-0.38%C), a block which is observed as having different contrasts under optical microscopy contains two groups (sub-blocks) of laths which are of two K-S variants with a misorientation of about 10 degrees. On the other hand, in the high carbon alloy (0.61%C), a block consists of laths of a single K-S variant. (C) 2003 Acta Materialia Inc. Published by Elsevier Science Ltd. All rights reserved.
