Abstract

Electron-spin resonance was studied in the Cr21Ni16Mn7 and Cr20Ni16Mn6 austenites with different content of nitrogen and carbon. Measurements were made in the temperature region 10-300 K. Temperature dependences were obtained for the absorption-derivative signal parameters such as the intensity I(T), the width DELTAH(T), and the asymmetry parameter R(T). Theoretical analysis of the signal shape revealed that its temperature dependence is equivalent to its dependence on the inverse length of electron diffusion delta(e) through the skin layer delta, if the value (deltadelta(e)) is constant while the temperature changes. Thedependence of the electron-state density on the Fermi surface D(epsilon(F)) upon the solutes content is deduced from the fitting of theoretical and experimental curves I(T), DELTAH(T), and R(T). It was established that D(epsilon(F)) increases in nitrogen austenite and decreases in carbon austenite with the growth of nitrogen and carbon concentration.
