Phases and interfaces in the cr-fe-si ternary system: x-ray diffraction and electron microscopy study

HIGHLIGHTS

SUMMARY

    In accordance with Cr-Fe-Si ternary phase diagrams, the position of the sample composition of FeCrSi4 is at the point 17 at% Cr: 17 at % Fe: 66 Si at.%. Fe-Si Cr-Si Phase Space Group; Lattice Parameters (nm) # ICSD Phase Space Group; Lattice Parameters (nm) # ICSD Fe3 Si Fm3m; a=0.5665; Fm3m; a=0.5662. α-FeSi2 phase with space group P4/mmm completely transforms into orthorhombic Cmca β-FeSi2 phase and silicon appears in the composition of the sample after 3 days of annealing at 1073 K. 3 of 18 of 17 . . .
