| In this paper we identified iron phases in three different samples of highly corrosion-resistant steel LC200N using the Mössbauer spectrometry which is particularly suited method for this purpose. Special emphasis is put upon magnetically active crystalline phases. The samples had different thermal history: (1) hardened, (2) hardened with consequent rapid quenching in liquid nitrogen, (3) non-hardened and prepared in a disc form: with two sides ("as cut" and polished). Both ferritic magnetic phases and non-magnetic austenite phase were found in these samples. Relative content ratios between these phases were determined for each type of the samples and their respective sides. Higher amount of magnetic phases was found in non-hardened sample and on polished sides of all samples in general. The elemental characterization was accomplished by neutron activation analysis. |
