Redistribution of Alloying Elements in Electron-Irradiated Iron-Based Fcc Alloys Studied by Hydrogen-Probe Mechanical Spectroscopy

Abstract

AbstractEffect of electron irradiation on substitutional ordering was studied in Fe-36.7 wt.% Ni invartype alloy and Fe-25.2 wt.% Cr-20.2 wt.% Ni austenitic stainless steel. It was shown that the fine structure of the hydrogen Snoek-type peak in invar changes after irradiation to a fluence of 1019 e−.cm−2 with electrons with an energy of 3 MeV as compared to the solution treated condition. Irradiation affects the temperature behavior of the shear modulus of invar. No significant effect of irradiation on hydrogen Snoek-type peaks was detected in stainless steel.
