Enhanced magnetic refrigeration properties in Mn-rich Ni-Mn-Sn ribbons by optimal annealing
The influence of annealing time on temperature range of martensitic phase transition (ΔT(A-M)), thermal hysteresis (ΔThys), magnetic hysteresis loss (ΔMhys), magnetic entropy change (ΔS(M)) and relative refrigeration capacity (RC) of the Mn-rich Ni43Mn46Sn11 melt spun ribbons have been systematically studied. By optimal annealing, an extremely large ΔS(M) of 43.2 J.kg(-1)K(-1) and a maximum RC ...
متن کاملMagnetic properties and magnetic entropy change in Heusler alloys Ni 50 Mn 35 − x Cu x Sn 15
The influence of Cu substitution for Mn on magnetic properties and magnetic entropy change has been investigated in Heusler alloys, Ni50Mn35−xCuxSn15 (x = 2,5 and 10). With increasing Cu content from x = 2 to x = 5, the martensitic transition temperature, TM , decreases from 220 K to 120 K. Further increasing Cu up to x = 10 results in the disappearance of TM . For samples Ni50Mn33Cu2Sn15 and N...
متن کاملMagnetic superelasticity and inverse magnetocaloric effect in Ni-Mn-In
Applying a magnetic field to a ferromagnetic Ni50Mn34In16 alloy in the martensitic state induces a structural phase transition to the austenitic state. This is accompanied by a strain which recovers on removing the magnetic field, giving the system a magnetically superelastic character. A further property of this alloy is that it also shows the inverse magnetocaloric effect. The magnetic supere...
متن کاملMartensitic transformation and magnetic properties of Co–Ni–Al shape memory alloy ribbons
We report on the magnetic and martensitic transformation properties of Co39Ni33Al28 ferromagnetic shape memory alloy ribbons. We found that the phase formation of Co39Ni33Al28 is strongly dependent on the method of preparation. The conventional as-cast ingot sample contains a large amount of the γ phase embedded in the primary β phase, while melt-spun ribbons contain the pure β phase. Co39Ni33A...
متن کاملSynthesis, structure, and mechanical properties of Ni–Al and Ni–Cr–Al superalloy foams
Reticulated nickel foams were alloyed with 8–9 wt% Al or 14–18 wt% Cr and 5–9 wt% Al in a three-step method consisting of (i) gas-phase deposition of Cr and/or Al onto the struts of a pure Ni foam by pack-cementation at 1000 C; (ii) homogenization at 1200 C to remove concentration gradients and to solutionize the alloyed struts; (iii) aging at 900 C to form c0 precipitates within the struts. Th...
