Effect of Stress-Induced Martensite Aging on Martensite Variant Reorientation Strain in NiMnGa Single Crystals

Shape Memory and Superelasticity, 2019
This work presents the effect of stress-induced martensite aging (SIM-aging) on the functional properties of Ni53Mn25Ga22 (at.%) single crystals, oriented along the [001]L21-direction. The most effective regime of SIM-aging occurred under a compressive stress of 175 MPa along the [110]L21||[100]L10-direction at 423 K, for 2 h, which induced the high ...

A Miniature Energy Harvesting Device Using Martensite Variant Reorientation

Materials Science Forum, 2013
This paper presents a miniature energy harvesting device that makes use of stress-induced cyclic martensite variant reorientation in a Ni-Mn-Ga single crystal of 0.3x2x2 mm³ size. The stress- and magnetic field-induced reorientation is investigated for single crystalline Ni50.2Mn28.4Ga21.4 specimens of 0.3 mm thickness that are cut along the (100 ...

Martensite Variant Reorientation of NiMnGa/Silicone Composites Containing Polystyrene Foam Particles

Advanced Materials Research, 2011
Effect of elastic modulus of matrix on ferromagnetic motion of NiMnGa particles was investigated for NiMnGa particles embedded silicone matrix composites with or without containing polystyrene form particles (PFPs), which are regarded as pores. NiMnGa single crystal was fabricated by a floating zone method and a cube-shape particle was fabricated with ...

Energy harvesting using martensite variant reorientation mechanism in a NiMnGa magnetic shape memory alloy

Applied Physics Letters, 2007
Magnetic shape memory alloys demonstrate significant potential for harvesting waste mechanical energy utilizing the Villari effect. In this study, a few milliwatts of power output are achieved taking advantage of martensite variant reorientation mechanism in Ni51.1Mn24Ga24.9 single crystals under slowly fluctuating loads (10Hz) without optimization in ...
