摘要：
Isothermal sections of the Al–Zn–Bi–Fe quaternary system at 600 °C with fixed Al content of 75 at.% and fixed Zn content of 50 at.% were determined by scanning electron microscopy coupled with energy-dispersive x-ray spectroscopy and x-ray powder diffraction analysis. One four-phase region and four four-phase regions were identified in the 75 at.% Al and 50 at.% Zn sections, respectively. The Bi-poor L1 phase and Bi-rich L2 phase are in equilibrium with (Al), FeAl3, Fe2Al5, α-Fe, and δ, respectively. No new quaternary phase was found in these two sections. Bi is almost insoluble in all Fe–Al and Fe–Zn compounds.
