Influence of nitrogen on the tendency to packing defect formation and the temperature dependence of the thermoelectromotive force in Fe-Cr alloys

The influence of nitrogen on the absolute coefficient of thermoelectromotive force in steel and the tendency of the material to form packing defects is studied. The absolute coefficient of the thermo-emf increases monotonically with increasing nitrogen concentration. The tendency to form packing defects increases monotonically with increasing nitrogen concentration in the range where the austenite solid solution is stable. Near the phase transition (austenite-martensite) this tendency increases sharply. The experiments described indicate that nitrogen influences the electron subsystem of the metal.
