提出了一种基于电子背散射衍射分析确定马氏体和贝氏体与母奥氏体间位向关系的新方法。该方法不需要残余奥氏体就能准确测定取向关系，适用于低合金碳钢中板条马氏体和贝氏体的测定。对于板条马氏体，无论碳含量如何，密排方向之间的角度约为3度，而密排平面之间的角度随着碳含量的增加而变小。(C)2009 Acta Materialia Inc.由爱思唯尔有限公司出版。保留所有权利。
A new method to determine the orientation relationship between martensite and bainite with the parent austenite is developed based on electron backscatter diffraction analysis. This method can determine the orientation relationship accurately without the presence of retained austenite, and is applicable to lath martensite and bainite in low-alloyed carbon steels. The angles between close-packed directions are about 3 degrees for lath martensite regardless of the carbon content, while the angles between close-packed planes become smaller with increasing carbon content.
