Abstract
The Fe-30Ni alloy investigated exhibits a single-phase austenitic structure. In this alloy the martensitic transformation can occur both during quenching and plastic deformation. Thermo-mechanical treatments applied for Fe-30Ni can result in the formation of a wide range of microstructures with various martensite morphologies and volume fractions, what gives a possibility to achieve different properties of the alloy. In the present work a microstructural analysis of the deformed Fe-30Ni alloy was performed after several variants of thermo-mechanical treatment. The microstructure was examined using light microscopy (LM) and transmission electron microscopy (TEM). The determination of the volume fraction of martensite formed in different thermo-mechanical treatments was performed using stereological methods and magnetic measurements. The mechanical properties of the alloy investigated were determined in tensile tests.

Key words
iron alloys, deformation structure, martensitic phase transformation, light microscopy, transmission electron microscopy, rolling
