Composition effects on the fcc-hcp martensitic transformation and on the magnetic ordering of the fcc structure in Fe-Mn-Cr alloys
(Elsevier Ltd, 2017-02-15)
This paper presents an experimental study on the fcc/hcp martensitic transformation temperatures (MTTs) and Néel temperatures (TN) of the fcc phase of Fe-Mn-Cr alloys. A wide range of chemical compositions (13.7 < Mn < 27.5 wt.% ...
Shape memory effect and pseudoelasticity in Fe-Mn-based alloys
(Springer, 2016-12-16)
Several Fe-based alloys are being considered as potential candidates for applications which require shape-memory behavior or superelastic properties. The possibility of using fabrication methods which are well known in the ...
Role of Mn and Cr on structural parameters and strain energy during FCC-HCP martensitic transformation in Fe-Mn-Cr shape memory alloys
(Elsevier, 2018-02-10)
Fe-Mn-based alloys show the shape memory effect which is mainly related to the FCC-HCP martensitic transformation. Cr is one of the additional elements which improve the properties of these alloys. In the present work ...
High temperature cyclic oxidation behavior of a low manganese Fe12Mn9Cr5Si4Ni-NbC shape memory stainless steels
(2021-03-15)
High amounts of Mn in Fe-Mn-Si-Cr-Ni shape memory stainless steels are detrimental for oxidation resistance at high temperatures. However, in order to maintain the shape memory effect of these alloys the content of manganese ...
A Short Review on the Effect of Cr on the fcc–hcp Phase Transition in Fe–Mn-Based Alloys
(Springer, 2020-06)
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 ...
