Abstract

The evolution of strain, magnetic domain structure, and martensite microstructure during compressive stress loading and unloading of Ni2 MnGa was studied using a phase-field model at several selected magnetic fields. We observed a typical quasiplastic behavior at zero field and a pseudoelastic behavior at 300 kA/m. At an intermediate field, 150 kA/m, the stress-strain relation is partially pseudoelastic. It was demonstrated that the magnetic domain structure has little influence on the recovered strain while the demagnetization factor impacts the strain reversal.
