Title: | Hydrogen effect on the sigma-phase in Fe53.8Cr46.2 | Authors: | Cieslak, J. Costa, B. F. O. Dubiel, S. M. Fruchart, D. Skryabina, N. E. |
Keywords: | Fe-Cr alloy; Metal hydride; Structure transformation | Issue Date: | 1-Sep-2008 | Citation: | Journal of Alloys and Compounds. In Press, Corrected Proof: | Abstract: | Investigation of the stability and properties of a sigma-phase type compound Fe53.8Cr46.2 after electrochemical hydrogen treatment was made using X-ray diffraction and 57Fe Mössbauer spectroscopy techniques. The amount of the hydrogen uptake was estimated to be equal to ~1.2H per unit formula, and its presence leads to an anisotropic cell parameter expansion. However, the hydrogenated state appears as metastable with reference to the aged samples analyzed a few days to months after loading with hydrogen. | URI: | https://hdl.handle.net/10316/4337 | DOI: | 10.1016/j.jallcom.2007.11.149 | Rights: | openAccess |
