| Abstract Scope |
A series of Fe-Mn-Al-C alloys were evaluated in order to determine the effect of composition variation on resulting properties. Whereas past studies have examined the sensitivity of mechanical properties to changing a single element in the composition in these alloys, this study evaluated covariance of the major elements: Mn, Al, and C. In this study, a series of ingots were prepared according to a two-factor design of experiments that were all expected to be age hardenable through precipitation of kappa-carbide. Aging kinetics and mechanical properties will be discussed in terms of microstructure. Complimentary CALPHAD modeling results and challenges in accurate composition evaluation will also be discussed. |
