Abstract

A new iron-rich intermetallic, Al m Fe, is observed, for the first time, in the important A206 (Al-4.6Cu-0.5Fe) cast alloy and identified using electron backscattered diffraction (EBSD) and a transmission electron microscope (TEM). Results show that Chinese script Al m Fe can precipitate as the dominant iron-rich intermetallic at high iron content (0.5 wt pct) and low cooling rate (0.2 K/s). EBSD and TEM results confirmed that Al m Fe has body-centered-tetragonal structure with an average m of approximately 4.2.
