| Outline of Final Research Achievements |
We conducted XAFS and DAFS at SAXS regions of the Mg85Y9Zn6 ternary alloys, which has been known as a representative alloy system of LPSO structures having 18R structure. Since there are few XAFS reports showing local environmental structures of 18R- LPSO, we have examined the local structures around Zn and Y aroms using the both K edge XAFS signals. The XAFS analysis for the samples cast by ingot metallurgy showed that the atomic structures around Zn are strongly distorted, while those for Y is not so distorted. The present results are found to be in qualitatively good agreement with what have been found by TEM/ABF analysis by Kishida et al and Abe et al, while the results on earlier stage of LPSO formation is left unsolved due to reproducibility problems stemming from sample conditions.
