基于电子背散射衍射，提出了一种新的、简单的确定固体中各相之间取向关系的方法。该方法成功地解释了在Mg 10 wt.%的Al2Y形核颗粒上生长的Mg晶粒的异质形核的晶体学。Y合金。确定了两个可重复的OR，它们完全符合边缘到边缘匹配模型的先前预测。这证实了Al2Y是这种类型合金的有效晶粒细化剂。(C)2009 Acta Materialia Inc.由爱思唯尔有限公司出版。保留所有权利。
Based on electron backscatter diffraction, a novel and simple method was developed to determine orientation relationships (ORs) between phases in solids. The method was successful in explaining the crystallography of heterogeneous nucleation of Mg grains grown on Al2Y nucleation particles in an Mg 10 wt.% Y alloy. Two reproducible ORs were identified and they completely agree with previous predictions from the edge-to-edge matching model. This confirms that Al2Y is an effective grain refiner for this type of alloy. (C) 2009 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
