Magnetic Properties and Structural Phase Transformations of NiMnGa Alloys
The magnetic properties and structural phase transformations of Heusler alloys Ni2+ Mn1 Ga and Ni2 Mn1+ 2Ga1+ 2 were investigated. It was found that the martensitic transformation temperature increases and the Curie temperature decreases with decreasing Mn concentration in the Ni2+ Mn1 Ga system, but the magnetic properties decrease faster than those do in the Ni2 Mn1+ 2Ga1+ 2 system. It sugges...
متن کاملEffect of Fe addition on transformation temperatures and hardness of NiMnGa magnetic shape memory alloys
In recent years, ferromagnetic shape memory alloys (FSMAs) have been widely investigated in many countries [1–4]. Of the developed FSMAs, NiMnGa alloys have been found to exhibit nearly 10% magnetic-fieldinduced strain which is the maximum obtained MFIS in these FSMAs [5]. Based on NiMnGa alloys, researchers have developed new ferromagnetic shape memory alloys, i.e., NiMnFeGa alloys [6, 7]. The...
متن کاملMartensitic Transformation in NiMnGa Single Crystals: Numerical Simulation and Experiments
In this article, we develop a continuum mechanical model to simulate deformation and phase transformation processes in shape memory alloys. The model is based on a detailed description of the stored energy. Furthermore, the energy dissipation due to phase transformations is taken into account via the maximum-dissipation principle. The results from the 3D numerical simulations of stress induced ...
متن کاملInter-martensite strain evolution in NiMnGa single crystals
Stress-induced martensitic transformations are clarified in classes of NiMnGa alloys which undergo the stress-free, thermal-induced inter-martensite transformation austenite (A) pre-martensite (PM) martensite. This study implements a comprehensive experimental approach, including analysis of the strain–temperature and stress–strain response, which discloses stress-induced inter-martensite trans...
