- Abstract
This research project was focused on understanding the production and response to heat treatment for a Fe8Mn2Al2Si0.3C steel alloy. These alloys can be heat treated to produce multiphase microstructures containing ferrite, austenite, martensite, and/or iron carbide. A previous project examined "high" carbon contents (0.5 wt% and 0.75 wt%), where the microstructure consisted primarily of stabilized austenite and heat treatment could produce austenite plus ferrite dual-phase microstructures that had higher hardness and, presumably, higher tensile strength (Druschitz in Inter Metalcast, 2023. https://doi.org/10.1007/s40962-023-01000-1). In this study, we examined a "low" carbon content (0.3 wt%), where the microstructure was primarily martensite and heat treatment could produce martensite plus ferrite and/or austenite. Therefore, this lower carbon content Fe8Mn2Al2Si0.3C steel had higher hardness (and presumably greater strength) compared to the higher carbon content steels.
