STUDY OF INFLUENCE OF REFRACTORY ELEMENTS ON THE SELF-DIFFUSION OF IRON WITH THE HELP OF RADIOACTIVE ISOTOPES,

Abstract

The relation of the coefficient of self-diffusion D of iron in iron-nickel, molybdenum, niobium, titanium and vanadium were determined. The addition of nickel and vanadium leads to an increase of the diffusion mobility of atoms of iron to a decrease of the pre-exponential multiplier and to a decrease of the energy of self-diffusion. The addition of molybdenum, niobium and titanium leads to a decrease of the diffusion mobility of iron, to an increase of the pre-exponential multiplier and to a strong increase of the heat of diffusion. There are data concerning an increase of the temperature of recrystallization and long durability of iron alloys during alloying with these elements. (Author)
