Experimental Study on the Magnetomechanical Characteristics of Ni-Mn-Ga Ferromagnetic Shape Memory Alloy Single Crystals
Magnetic shape memory properties of Ni-Mn-Ga single crystals were characterized by measurement of stress-induced martensite reorientation under constant magnetic fields. Also magnetic field-induced strain as a function of the applied magnetic field under different constant compressive stress levels has been investigated. All the experiments were performed at room temperature in which the sample...
متن کاملFinite Element Modeling of Magneto-superelastic Behavior of Ferromagnetic Shape Memory Alloy Helical Springs
The previous study by thefor the finite element analysis of superelastic, large deformation behaviors of one-dimensional shape memory alloy (SMA) devices is extended to the magneto-superelastic analysis of ferromagnetic shape memory alloy (FSMA) devices. The commercial code ANSYS/ Emag for magnetic analysis is combined with the SMA superelastic analysis program developed by the authors. The num...
متن کاملMAGNETOELASTIC COUPLING IN NiMnGa FERROMAGNETIC SHAPE MEMORY ALLOY
Title of Document: MAGNETOELASTIC COUPLING IN NiMnGa FERROMAGNETIC SHAPE MEMORY ALLOY Peng Zhao, Doctor of Philosophy, 2006 Directed By: Professor, Manfred Wuttig, Department of Materials Science and Engineering NiMnGa alloys have attracted extensive attention because their ferromagnetic characteristic provides an additional degree of freedom to control both the shape memory effect and the mult...
متن کاملMicrostructure and precipitates in annealed Co38Ni33Al29 ferromagnetic shape memory alloy
Transmission electron microscopy was performed to investigate the microstructure and precipitates in the annealed Co38Ni33Al29 ferromagnetic shape memory alloy. Apart from the dendritic secondary phase in the austenite matrix, micron-sized (up to 100 lm) fcc-based precipitates with partial c0 L12 ordering and containing none, one or three {111}p parallel twin planes were found. The orientation ...
متن کاملFatigue-Crack Growth Behavior in the Superelastic and Shape-Memory Alloy Nitinol
This article presents a study of fatigue-crack propagation behavior in Nitinol, a 50Ni-50Ti (at. pct) superelastic/shape-memory alloy, with particular emphasis on the effect of the stress-induced martensitic transformation on crack-growth resistance. Specifically, fatigue-crack growth was characterized in stable austenite (at 120 8C), superelastic austenite (at 37 8C), and martensite (at 265 8C...
