Phase equilibria of the Fe-Ni-Si system at 850 degrees C

• By means of X-ray diffraction, metallography, scanning electron microscopy with energy dispersive Xray analysis, and electron probe microanalysis, the constitution of the ternary Fe-Ni-Si system at 850 degrees C over the entire composition range was established with 24 alloys. Ten of the three-phase equilibria were well determined at 850 degrees C. The existence of the ternary compound Fe5Ni3Si2 (tau(1)) with a cubic crystal structure at 850 degrees C is confirmed. The homogeneity ranges were measured and the lattice parameters were determined for most observed phases.
