Abstract Scope |
Mg alloys containing Zn and rare earths (RE) have been received increasing attention owing to their superior mechanical properties. It has been reported that Zn and RE form clusters, which should play an important role in strengthening these alloys. X-ray fluorescence holography (XFH) is a powerful tool to visualize a three dimensional atomic arrangement around a selected element. XFH has been applied to Mg-Zn-Y alloys to characterize the L12-type Zn6Y8 clusters. However, XFH requires mm size single crystals, which has been restricted the range of application of this technique. In particular, almost all Mg-Zn-RE alloys can not be obtained in the single crystal form. In this study, we attempt to apply XFH technique to a grain of polycrystalline Mg97Zn1Gd2 using a micro beam X-ray and a two dimensional detector to record Zn-Kα holograms. We will discuss the pattern of the obtained hologram in comparison with the calculated results. |
