Abstract
We report an analysis by means of Mössbauer spectroscopy on a 9 Cr steel submitted to a tempering process at 780°C Spectra of several samples with different tempering times obtained at room temperature are fitted and a study on existent phases is made From the former analysis we infer the existence of different neighbors of the Fe atom governed by the concentration of alloying elements In particular we analyze the behavior of Cr as the main substitutional atom An additional measurement of samples at low velocities is made aiming to reveal the existence of precipitated carbides Finally a comparison between samples is performed in order to obtain a detailed study of the effect of tempering time on hyperfine parameters
