Phase and microstructural analysis of hot rolled FeNi42 sheet, its response in magnetic and mechanical properties

Popis výsledku v původním jazyce

Inclusions unavoidably existing in steels and consequently also in final products obtained by e.g. rolling markedly affects the physical properties. This paper is devoted to investigation of FeNi42 steel hot rolled into a sheet form. The structural and phase analysis is done by scanning electron microscopy, X-ray diffraction, and Mössbauer spectroscopy completed by magnetic and hardness measurements. The results yield an inhomogeneous nickel distribution in the sheet resulting in a formation of the intermetallic Ni3Fe phase. A depletion of sheet surface by nickel leads to an intensive surface oxidation; its thickness increases in the direction of sheet edges. The non-metallic oxide inclusions are concentrated predominantly at grain boundaries, which contribute to an easier cracking. The formation of Ni3Fe affects a small increase in saturation magnetization. The oxides and consequently cracks formation cause magnetic hardening as can be seen on an increase of the structurally sensitive
