Special Features of Analysis and Control of Concentration Inhomogeneity of Complexly Modified Industrial Materials by the Method of Secondary-Ion Mass Spectrometry

Resumo

Concentration inhomogeneity in iron-carbon alloys is analyzed and controlled. It is shown that application of secondary-ion mass spectrometers with about 200 resolution with respect to the mass numbers and a comparatively large diameter of the primary ion beam (1 – 2 mm) gives results required for development and control of processes of structure formation in modified alloys and of changes in their physical and mechanical properties.
