phase transformationsalloymagnetic transitionsmartensite transitionsThe effect of ordering on the thermal characteristics of the magnetic and martensite transitions in the Fe-Pt alloy with a composition close to stoichiometric FePt composition is analyzed. It is found that a transition to a partly ordered...

In Fe 74.5 Pt 25.5 , however, the antiferrodistortive phase transition temperature is enhanced due to tetragonal strain preceding the martensitic transition. In Fe 77 Pt 23 a precursor driven premartensitic phase transition is not observed. The structure of the martensite is, however, influenced ...
Further, all the substituted materials which we have studied here are likely to undergo martensite transition. In this work, we have reported how the stability of the austenite and martensite phase varies with the extent of substitution by Fe as well as Cr at the Mn site. Further, we study...
transition metalsFerromagnetic shape memory alloys are a kind of multiferroic materials, in which a ferroelastic domain (variant in the martensite phase) and a magnetic domain are closely correlated. One interesting phenomenon caused by this correlation is the rearrangement of martensite variants by ...
This strain is considered as a typical precursor of the transformation to bct martensite. Specific heat measurements, performed at low temperatures on both crystals confirm the neutron scattering results and reveal considerable enhancement of the low energy phonon density of states in the ordered ...
