In this paper, the constitution of the ternary system Al-Fe-Si is reinvestigated over the entire composition range by X-ray diffraction (XRD), differential thermal analysis (DTA), and scanning electron microscopy/energy dispersive x-ray (SEM/EDX).Abstract:
The constitution of the ternary system Al-Fe-Si is reinvestigated over the entire composition range by X-ray diffraction (XRD), differential thermal analysis (DTA), and scanning electron microscopy/energy dispersive X-ray (SEM/EDX). The liquidus projection obtained shows equilibria among nine ternary phases. Except for the occurrence of the three additional ternary phases not recognized at the time, the previous work is found to be accurate in most details. In the isothermal section at 550 °C, an additional ternary phase occurs for which the indexed X-ray powder diffraction pattern is presented. Crystal structures reported for the other phases are all confirmed.read more

TL;DR: In this article, the inconsistency between the measured and computed enthalpies of formation via CALPHAD method for the ternary compounds is traced to the Fe-Si system in which there is a disagreement between the experimental enthalpy of formation and CALPAD type one.
