MÖSSBAUER SPECTROSCOPY AND ITS APPLICATION TO THE CHARACTERIZATION OF HEAT TREATED PARTS

The primary objective of this contribution is to present the application of Mössbauer spectroscopy in the field of iron-containing material research and quality control as a non-destructive testing (NDT) method – NDC/NDE/NDI. The application of Mössbauer spectroscopy (MS) in the domain of steel research, heat treatment and inspection of structural components by non-destructive testing (NDT) facilitates the characterization of the phase composition of steels. This technique can be used to analyze whole machine components, their surfaces, sections and cuttings, which are usually prepared for metallographic analysis. The method is useful in industry for research and development, input and output quality control, etc. The present article principally concerns itself with the presentation of the use of MS in practice on selected retained austenite (RA) evaluation tasks.
