摘要: The Al-rich part of the Fe-Al phase diagram between 50 and 80 at.% Al including complex intermetallic phases Fe5Al8 (e), FeAl2, Fe2Al5, Fe4Al13 was re-investigated in detail. A series 19 alloys produced heat-treated at temperatures range from 600 to 1100 °C for up 5000 h. obtained data were further complemented by results a number diffusion couples, which helped determine homogeneity ranges Fe4Al13. All microstructures inspected scanning electron microscopy (SEM), chemical compositions equilibrium as well probe microanalysis (EPMA). Crystal structures variation lattice parameters studied x-ray diffraction (XRD) differential thermal analysis (DTA) applied measure all types transition temperatures. From these results, revised version constructed.
