研究了高Zn含量Mg-Zn合金中六方密排α-Mg（Zn）凝固组织的枝晶生长取向和三维形貌。使用电子背散射衍射和X射线同步辐射断层扫描相结合，我们已经证明，α-Mg（Zn）枝晶生长与六个二级分支结构背后的推进枝晶尖端。讨论了枝晶和前进枝晶的晶体学。(c)2012 Acta Materialia Inc.由爱思唯尔有限公司出版。保留所有权利。
Dendritic growth orientations and three-dimensional morphologies of hexagonal close-packed alpha-Mg(Zn) solidification microstructures were studied in an Mg-Zn alloy with a high Zn content. Using a combination of electron backscatter diffraction and X-ray synchrotron tomography, we have demonstrated that alpha-Mg(Zn) dendrites grow with a six secondary branched structure behind the advancing dendrite tip. The crystallography of the branches and advancing dendrite is discussed. (c) 2012 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
