Some features of grain boundary segregations in sensitized austenitic stainless steel (original) (raw)
ADS
Abstract
The paper presents results of Auger spectroscopy on fracture surfaces of the austenitic stainless steel 16Cr15Ni3Mo1Nb subjected to thermal sensitization in the temperature range 550-700°C followed by doping with deuterium to produce grain boundary brittle fracture by in situ tensile testing. Non-uniformity of Cr distribution and segregation of P, Ni, N and S in the grain boundary regions, depletion of Cr and noticeable replacing of C by high-level P and S have been shown.
