Abstract
Phase equilibria in the Al corner of the Al-Fe-Mn-Si system at 550 deg rees C have been explored. Twenty-six quaternary alloys were prepared and analyzed by microprobe analysis. Elemental powders were mixed unde r air and molten at 1000 degrees C under argon flux. These specimens r eceived a heat treatment at 550 degrees C during 4 to 12 weeks and fin ally were water quenched. A four-phase region, where Al, Si, alpha-Al( Fe,Mn)Si, and beta-Al(Fe,Mn)Si are in equilibrium with each other, was found. The presence of a single-phase alpha-Al(Fe,Mn)Si region, start ing in the Al-Mn-Si subsystem and extending toward the Al-Fe-Si subsys tem, could be confirmed. Some problems concerning the fit of the quate rnary system with its ternary Al-Fe-Mn subsystem remain to be solved.
