Abstract: Types of Fe-Mn-Al-C steel and the action mechanisms of alloying elements were systematically introduced, and the influences of different heat treatment processes on microstructure and mechanical properties of the Fe-Mn-Al-C steel were reviewed. Combining with the current research status of the role of niobium alloying in steels, it is proposed that by adding Nb elements, the precipitation of the second phase NbC in the Fe-Mn-Al-C steel can be promoted, and the grains can be refined, thus presenting the application prospects of Nb alloying for improving the properties of the Fe-Mn-Al-C steel.

Key words: Fe-Mn-Al-C low-density steel, Nb alloying, heat treatment, microstructure, mechanical properties
