Abstract

When the present alloy was aged at 550°C, Hägg carbides (M5C2-type carbides) formed at a/2⟨100⟩ anti-phase boundaries of the D03 domains. The Hägg carbide has never been observed by previous workers in FeMnAlC and FeMnAlCrC alloy systems. The orientation relationship between Hägg carbide and D03 matrix was determined to be (\\bar510)M5C2||(1\\bar10)D03 and (13\\bar4)M5C2||(10\\bar2)D03. The orientation relationship between Hägg carbide and bcc-type phase has also never been reported before.
