Abstract
AbstractThe isothermal section of the Fe–Al–Ce system at 600 °C was determined by means of scanning electron microscopy coupled with energy dispersive spectroscopy and X-ray powder diffraction. Twenty three-phase regions were confirmed experimentally, and two three-phase regions could be deduced in this section. Five ternary compounds, i. e., τ1, τ2, τ3, τ5, and τ6, exist at 600 °C. The Fe2Ce phase contains 6.6 at.% Al in the Fe–Al–Ce system. The Fe solubility in α-Al, αAl11Ce3, αAl3Ce, Al2Ce, AlCe, and AlCe3 is approximately 1.7 at.%, 1.1 at.%, 1.2 at.%, 1.3 at.%, 5.8 at.%, and 0.1 at.%, respectively, and the solubility of Ce in α-Al, FeAl3, Fe2Al5, FeAl2, and FeAl is approximately 0.1 at.%, 1.2 at.%, 1.9 at.%, 0.9 at.%, and 3.7 at.%, respectively.
