ANALYSIS OF CHEMICAL COMPOSITION AND STUDY OF SURFACE TOPOGRAPHY OF NiMnGa ALLOY IN DELIVERY CONDITION

J. Kaleta, D. Lewandowski, D. Sawicka
Abstract:
The object of this work was an examination of the microstructure and mapping of chemical elements at the surface of NiMnGa. This material is distinguished by magnetostriction (even 6% of its length), shape memory and magnetocaloric effect. The sample was mounted and then examined with scanning electron microscope using detectors: SE , BSE and EDX (mapping). The structure on the obtained images can be defined as martensitic. The review of microcracks at the surface showed a non-chaotic distribution. The results of mapping of the chemical elements at the surface confirmed the uniform distribution of component.
