In this note we describe an application of backscattering 57Fe Mossbauer spectroscopy for determination of the austenite content in steels, where the surface analysed thickness is ∼20 µm. The method enables rapid determination of the residual aust

Speed of data processing is regarded as a crucial parameter in the nuclear physics experiment, where a dead time elimination or reduction is needed. In the case of computer-based systems, fast data processing algorithms are necessary to be exploited
