Cobalt-base ferromagnetic shape memory alloys
Single crystalline and polycrystalline CoxNiyGa100-(x+y), 41<xCo<62 and 19.3<xNi<32.7 [at%], Ferromagnetic Shape Memory Alloys (FMSMAs) have been produced in the range of the Heusler-type composition. Elasto-mechanical properties have been analyzed for the annealed and quenched states, respectively. The mechanical spectroscopy data show the occurrence of martensitic phase transformations with t...
متن کاملEffects of Annealing on the Martensitic Transformation of Ni-Based Ferromagnetic Shape Memory Heusler Alloys and Nanoparticles
We report on the effects of annealing on the martensitic phase transformation in the Ni-based Heusler system: Mn50Ni40Sn10 and Mn50Ni41Sn9 powder and Co50Ni21Ga32 nanoparticles. For the powdered Mn50Ni40Sn10 and Mn50Ni41Sn9 alloys, structural and magnetic measurements reveal that post-annealing decreases the martensitic transformation temperatures and increases the transition hysteresis. This m...
متن کاملFerromagnetic shape memory alloys: Alternatives to Ni–Mn–Ga
This paper intends to review the state-of-the-art in the field of ferromagnetic shape memory alloys different than Ni–Mn–Ga, developed in the ast years. It starts with the effects of additions of different fourth elements to Ni–Mn–Ga and continues with the review of other Heusler (or B2) i-based and Co-based alloy systems, like Ni–Mn–X, Ni–Fe–Ga, Co–Ni–Al and Co–Ni–Ga alloys. Finally, ferromagn...
متن کاملMagnetic field-induced reversible actuation using ferromagnetic shape memory alloys
This paper presents a simple method to examine whether a ferromagnetic shape memory alloy can be used as an actuator by controlling the transformation temperature by magnetic field. Both Fe–Pd and NiAlCo alloys are studied. The analysis results show the recently discovered alloy of NiAlCo cannot be used. Although an Fe–Pd alloy can be used, in principle, for magnetic field actuation, the work e...
متن کاملStructure Calculations Applied to Shape Memory Alloys
Despite the potential of these alloys and the amount of patents, successful industrial and commercial applications of Shape Memory Alloys (SMA) remain exceptions. This can be explained by the lack of design tools able to dimension correctly SMA elements because the non elastic behavior of SMA lead the classical method of design to be inefficient. Furthermore, this behavior is strongly dependent...
