摘要

镁合金Mg85Zn6Y9因其优异的力学性能而备受关注。这些特性来自于掺杂剂Zn和Y原子的独特的Zn6Y8簇。近年来，Y和Zn浓度较低的Mg99.2Zn0.2Y0.6具有与Mg85Zn6Y9相似的优异力学性能，但由于浓度较低，难以形成完美的Zn6Y8团簇。为了研究Mg99.2Zn0.2Y0.6的团簇结构，我们采用了光电子全息技术。从y3d的全息图中，我们成功地获得了Zn原子的原子位置，并且原子位置与完美的Zn6Y8簇不同。

Local structure analysis of magnesium alloy Mg99.2Zn0.2Y0.6 by photoelectron holography

Mg alloy Mg₈₅Zn₆Y₉ has attracted attention because of its superior mechanical properties. These properties come from the unique Zn₆Y₈ cluster of the dopants Zn and Y atoms. Recently, Mg_99.2Zn_0.2Y_0.6, which has lower concentrations of Y and Zn, exhibits similar superior mechanical properties to Mg₈₅Zn₆Y₉, but it is difficult to form the perfect Zn₆Y₈ cluster because of low concentration. To investigate the cluster structure of Mg_99.2Zn_0.2Y_0.6, we carried out photoelectron holography. From the hologram of Y 3d, we successfully obtained the atomic positions of Zn atoms, and the atomic positions are different from the perfect Zn₆Y₈ cluster.

期刊介绍： Scripta Materialia is a LETTERS journal of Acta Materialia, providing a forum for the rapid publication of short communications on the relationship between the structure and the properties of inorganic materials. The emphasis is on originality rather than incremental research. Short reports on the development of materials with novel or substantially improved properties are also welcomed. Emphasis is on either the functional or mechanical behavior of metals, ceramics and semiconductors at all length scales.
