The paper describes experimental investigations depending on temperature of polycrystalline MSMA with composition of nominal Ni50Mn30Ga20. The aim for our future work is to find a way for the development of forming technology, which allows to produce a texture within the NiMnGa-material. The alloy was prepared by arc induction melting pure constituents and it was annealed for 48 h at 900 °C. The casting specimens were characterized by using EDX, optical microscopy and XRD. The benefit of the selected MSMA-composition was the high temperature of martensitic transformation, but a mixed structure (tetragonal and orthorhombic) was determinated by X-ray measurements.enmagnetic shape memory alloyNiMnGahot-rollingmartensitic transformationmagnetic field induced strainmagnetische FormgedächtnislegierungNiMnGaWarmwalzprozessmartensitische Umwandlungmagnetfeldinduzierte Dehnung620670conference paper
