Role of Mo in the local configuration and structure stabilization of amorphous steels, a Synchrotron X-ray diffraction and Mössbauer study Serrano Gutiérrez, Jorge Amorphous steels are promising materials with potential structural applications. The glass-forming ability (GFA) and mechanical properties of metallic glasses are intimately related to the local structure. In Fe-based alloys, Cr and Mo content seem to play a key role in stabilizing the amorphous atomic-level structure. Here we present a study on the effects of changing Mo content in Fe72−xC7Si3.3B5.5P8.7Cr2.3Al2Mox amorphous steels. We study the local structure of these alloys by Synchrotron X-ray diffraction and Mössbauer spectroscopy. The results show how the amorphous phase evolves from a ferromagnetic Fe-rich structure to a structure with predominance of paramagnetic environments with the increase of Mo content. The changes in the distribution of magnetic environments cannot be attributed only to the Fe–Mo substitution but to a change of local configuration in the amorphous phase. 2024-01-29T20:00:26Z 2024-01-29T20:00:26Z 2011 info:eu-repo/semantics/article Journal of Alloys and Compounds 509S (2011) S56–S59 https://uvadoc.uva.es/handle/10324/65238 10.1016/j.jallcom.2011.02.019 eng info:eu-repo/semantics/openAccess Elsevier SI
