The 450 °C isothermal section of the Zn-Al-Mo phase diagram

The 450 °C isothermal section of the Zn-Al-Mo phase diagram has been determined experimentally using scanning electron microscopy (SEM) coupled with energy dispersive x-ray spectroscopy and x-ray diffractometry. The focus of the work is the Zn-rich corner due to its relevance to galvanizing. The present study indicates that with the increasing Al content of alloys, the liquid phase is successively in equilibrium with the ternary extensions of intermetallic compounds of MoZn^sub 22^, MoZn^sub 7^, AlMO3, and Al^sub 8^MO3.[PUBLICATION ABSTRACT]
