Formation of Hagg Carbide in an Fe-30Mn-10Al-4Cr-0.45C Alloy

Abstract

When the present alloy was aged at 550 degrees C, Hagg carbides (M(5)C(2)-type carbides) formed at a/2 < 100 > anti-phase boundaries of the D0(3) domains The Hagg carbide has never been observed by previous workers in FeMnAlC and FeMnAlCrC alloy systems The orientation relationship between Hagg carbide and D0(3) matrix was determined to be ((5) over bar 10)(M5C2) // (1 (1) over bar0)(D03) and (13 (4) over bar)(M5C2) // (10 (2) over bar )D0(3) The orientation relationship between Hagg carbide and bcc-type phase has also never been reported before [doi 10.2320/matertrans.M2010055]
