The Oxidation of Fe-Al Alloys Containing Chromium, Nickel, or Manganese

Effects of Mn Contents on the Microstructure and Mechanical Properties of the Fe-10Al-xMn-1.0C Alloy

“…The alloys, Fe-(10 ± 0.2)mass%Al- (5,10,15,20,25,30,35,40)mass%Mn-(1.0 ± 0.05)mass%C, were melted in an air induction furnace under the N 2 atmosphere protection by using AISI 1008 low carbon steel, 99.7% pure electrolytic aluminum, 99.9% pure electrolytic manganese, and pure carbon powder. After melting, the alloys were poured at 1500-1520…”

The strengthening effect of (Ni,Fe)Al precipitates on the mechanical properties at high temperatures of ferritic Fe–Al–Ni–Cr alloys

“…The present work aims at combining the excellent oxidation resistance of ferritic Fe-Cr-Al alloys with the high-temperature strength of Fe-Ni-Al alloys with a high volume fraction of the B2-(Ni,Fe)Al phase. Cr was found to distribute mostly in the ferritic phase [5], where it Intermetallics 13 (2005) aids the formation of a protective alumina scale by reducing the necessary aluminium content [14]. The focus of the study lies on the mechanical properties in view of a possible application as high-temperature structural material.…”

Precipitation in ductile Fe–18Al–5Cr alloys with additions of Mo, W and C and effects on high-temperature strength

“…The Al content was maintained deliberately low for these alloys, in the hope of obtaining reasonable ductility in the as-cast state [35]. The Cr addition was made since this may improve ductility [40] as well as improving high-temperature oxidation resistance [41,42]. All alloys had additions of 0.1%Zr and 0.2%B, expected to form intergranular ZrB 2 particles which may be useful to retain relatively fine grain sizes during casting or subsequent processing.…”
