Formation of long-period nanostructural phases in Ni2MnGa-based L21 alloys with thermoelastic martensitic transitions
The crystalline structures of martensite phases in Ni2MnGa-based ternary alloys have been studied in a wide range of temperatures and compositions transmission and scanning electron microscopy, X-ray diffraction, and electron diffraction. It is found that long-period nanostructural phases with thin-plate morphology are formed as a result of martensitic transformation in Ni2MnGa-based alloys.
