ON THE PROBLEMS OF DECIPHERING THE REAL STRUCTURE OF THE (Sm_0,9Zr_0,1)Fe11Ti ALLOY PREPARED BY MELT SPINNING

This study discusses the crucial problems arising in deciphering the atomic structure of the (Sm0,9Zr0,1)Fe11Ti melt-spun intermetallic alloy. X-ray and neutron diffraction analysis reveal significant data discrepancies attributed to partial material amorphization. It is shown that standard phase analysis methods must be modified to characterize adequately the structural states in ThMn12-type systems after rapid quenching. A model of divacancy formation in a 3D-atom sublattice as a potential destructuring mechanism is proposed. Verification of the structural models will require additional research techniques.
