Effect of alloying chemistry on the lattice constant of austenitic Fe-Mn-Al-C alloys

Abstract In summary, the lattice constant of austenitic Fe-Mn-Al-C alloys as a function of composition has been determined. The addition of manganese, aluminum, or carbon increases the lattice constant of austenitic Fe-Mn-C alloys, but the addition of silicon decreases the lattice constant. The effect of aluminum and carbon on the increase in lattice constant are similar, while that of manganese is about one order of magnitude smaller.
