In this study, in situ neutron diffraction and internal friction techniques were combined to comparatively analyze the structural and functional properties of Fe-26Al alloy. The results revealed the relationship between thermal treatments, microstructure, phase transformations, and anelastic (internal friction) properties of the alloy.
In situ neutron diffraction and internal friction were combined for the comparative analysis of structural and functional properties of Fe-26Al alloy. Three different alloy states were studied: after rapid solidifica-tion in graphite mold, after annealing at 900 degrees C (0.5 h) and water quenching, after annealing at 450 degrees C (24 h) and slow cooling. Structural phase states and microstructure types were determined. The obtained results make it possible establishing the relationship between the thermal treatments, microstructure, phase transformations on the one hand and anelastic (internal friction) properties on the other.(c) 2022 Elsevier B.V.
