“…When aging occurs from 550 to 650 • C in Fermanal steels, carbides are distributed inside the austenitic matrix [11]. A. Prodhan and A. Chakrabarti [14] studied phase transformations during aging of Fe-Mn-Al-Si-C alloys that were treated at 1100 • C. They found precipitation of the Al(Fe,Mn)C x phase inside the austenite grain when aged between 500-800 • C. J. Heredia [13] observed globular and transgranular acicular carbide precipitates in the [11,[14][15][16]. In this study, the results of the tribological and microstructural behavior of two Hadfield and Fe-Mn-Al-C alloyed steels under aged conditions are presented for comparison, establishing the performance of Fe-Mn-Al-C steel (unconventional steel) under the effects of wear.…”

In this study, Fe-12.50Mn-1.10C-1.70Cr-0.40Mo-0.40Si-0.50(max)P-0.50(max)S (Hadfield alloy) and Fe-28.4Mn-0.86C-1.63Al-0.42Cu-1.80Mo-1.59Si-0.60W (Fermanal alloy) (Wt. %) in the aged condition were compared in terms of its tribological and microstructural properties. The x-ray diffraction (XRD) patterns were refined with the lines of the austenitic γ -phase, Chromium Iron Carbide (Cr 2 Fe 14 C), Iron Carbide (Fe 2 C), and Iron Oxide (Fe 0.974 O (II)) for the Hadfield alloy, and the lines of the austenitic γphase, martensite (M), Mn 1.1 Al 0.9 phase and iron carbide (Fe 7 C 3 ) for the Fermanal alloy. Mössbauer spectra were fit with two sites for the Hadfield alloy, which displayed as a broad singlet because of the austenitic disordered phase, and had a magnetic hyperfine field distribution, which corresponds to the Cr 2 Fe 14 C ferromagnetic carbides found by XRD. There were two paramagnetic sites, a singlet, which corresponds to the austenite disordered phase, and a doublet, which can be attributed to the Fe 7 C 3 carbide. The obtained Rockwell C hardness for aged Hadfield and Fermanal alloys were 43.786 and 50.018 HRc, respectively.
