Data on the solidus surface of the Al–Cr–Fe system in the range 58–100 at.% Al and on the cast alloys examined with metallography, x-ray diffraction, and differential thermal and electron microprobe analyses are used to construct the liquidus surface of this system on the concentration triangle and study the processes that occur during crystallization of its alloys. This has permitted the construction of the Al–Cr–Fe melting diagram in the range 58–100 at.% Al. The liquidus surface includes primary crystallization fields of four ternary compounds, eight solid solutions based on binary phases, and a solid solution based on aluminum. There are fourteen four-phase invariant equilibria involving a liquid phase (three eutectic, two peritectic, and nine transition equilibria) and eight three-phase invariant equilibria involving a liquid phase.
