Abstract

Abstract To obtain Zn-rich corner of the 450 °C isothermal section of the Zn–Fe–Al–P quaternary system, the 450 °C isothermal section of the Al–P–Zn ternary phase diagram was investigated experimentally again using scanning electron microscopy coupled with energy dispersive X-ray spectroscopy, and X-ray diffraction. The experimental results reveal that AlP is in equilibrium with L–Zn, α-Al, Zn 3P 2, and ZnP 2, respectively. P solubility in liquid Zn and in α-Al phases is limited. L–Zn + Zn 3P 2 + AlP, L-Zn + α-Al + AlP and Zn 3P 2 + ZnP 2 + AlP three-phase equilibria were well established in present work.
