Abstract

Hydrogen-charged stainless austenitic steel Cr18Mn20 alloyed with 0.88 mass% of nitrogen is studied using a magnetic spin resonance method. The steelis paramagnetic before as well as after hydrogen charging, which allows one to observe electron spin resonance (ESR). It is shown that hydrogen causes a significant increase of the signal from conduction electrons in the ESRspectrum (CESR), i.e., it increases the concentration of free electrons inthe alloy. Hydrogen charging results also in a stronger exchange interaction between free and localized electrons. The kinetics of desorption of hydrogen from the sample is studied and the value of the enthalpy of hydrogen migration in the crystal lattice is evaluated from the studies of the decay of the CESR signal.
