摘要：

The phase equilibria of the 700 degrees C isothermal section of the Al-Si-Fe-Cr quaternary system with Al fixed at 90 at.%, and the related Al-rich ternary systems, have been determined experimentally with scanning electron microscopy coupled with energy dispersive X-ray spectroscopy and X-ray diffractometry. Eight four-phase regions and a new quaternary compound named zeta are found in the 700 degrees C isothermal section of Al-Si-Fe-Cr quaternary system. The zeta phase is found to be in equilibrium with all phases in the section including the FeAl3, tau(5), tau(6), (Si), tau(1), Al4Cr, Al45Cr7 and H phases, as well as the liquid phase.
