Modulated structure in the martensite phase of Ni1.8Pt0.2MnGa: a neutron diffraction study [PDF]
Appl. Phys. Lett. 101, 171904 (2012), 2012 7M orthorhombic modulated structure in the martensite phase of Ni1.8Pt0.2MnGa is reported by powder neutron diffraction study, which indicates that it is likely to exhibit magnetic field induced strain. The change in the unit cell volume is less than 0.5% between the austenite and martensite phases, as expected for a volume conserving martensite ...

A two dimensional model for ferromagnetic martensites [PDF]
, 2005 We consider a recently introduced 2-D square-to-rectangle martensite model that explains several unusual features of martensites to study ferromagnetic martensites. The strain order parameter is coupled to the magnetic order parameter through a 4-state clock model.

Influence of intermartensitic transitions on transport properties of Ni2.16Mn0.84Ga alloy [PDF]
J. Phys.: Condens. Matter 16 (2004), pp. 1951-1961, 2004 Magnetic, transport, and x-ray diffraction measurements of ferromagnetic shape memory alloy Ni$_{2.16}$Mn$_{0.84}$Ga revealed that this alloy undergoes an intermartensitic transition upon cooling, whereas no such a transition is observed upon subsequent heating.

Structure and Phase Transition of Fe-Mn Alloy Powders Prepared by Gas Atomization [PDF]
Materials Research, 2015 In this paper we investigated the microstructure and phase transition of atomized Fe-(1.3, 7.9, 11.7 wt.%) Mn alloy powders. The results show that the main phases of Fe-1.3Mn, Fe-7.9Mn and Fe-11.7Mn powders are ferrite, α’-martensite+austenite, α ...

Macroscopic modeling of strain-rate dependent energy dissipation of superelastic SMAs considering destabilization of martensitic lattice [PDF]
Smart Materials and Structures, 29(2):025005, 2020, 2021 Superelastic shape-memory alloys (SMAs) are unique smart materials with a considerable energy dissipation potential for dynamic loadings with varying strain-rates. The energy dissipation depends on the latent heat generated by the austenitic-martensitic transformation and the convection of that heat.
