Cm. Chu et al., EFFECT OF ALLOYING CHEMISTRY ON THE LATTICE-CONSTANT OF AUSTENITIC FE-MN-AL-C ALLOYS, Scripta metallurgica et materialia, 30(4), 1994, pp. 505-508
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-Al-C alloys, but the addition of silicon decreases the lattice cons
tant. The effect of aluminum and carbon on the increase in lattice con
stant are similar, while that of manganese is about one order of magni
tude smaller.
