Resumen
The effect of Cr on the fcc–hcp martensitic
transformation in the Fe–Mn–Cr system has been discussed
considering different aspects: (a) the relative phase stabilities, (b) the magnetic order of the fcc phase, (c) the
structural parameters and volume change between fcc and
hcp, (d) the driving force of the martensitic transformation
and relevant thermodynamics quantities, (e) the thermal

The effect of Cr on the fcc–hcp martensitic
transformation in the Fe–Mn–Cr system has been discussed
considering different aspects: (a) the relative phase stabilities, (b) the magnetic order of the fcc phase, (c) the
structural parameters and volume change between fcc and
hcp, (d) the driving force of the martensitic transformation
and relevant thermodynamics quantities, (e) the thermal
cycling behavior, and (f) the pseudoelastic effect. Particularly, in this work it has been found that when Cr content
increases, the effect of cycling on the energy barrier
decreases. This may be explained by a small volume
change, which could lead to a slighter introduction of
plastic deformation during thermal cycling through the
martensitic transition. [--]
