Abstract
Auger electron spectroscopy and energy filtering TEM were used to study alloying element distributions in the vicinity of matrix-TiO2 dispersoid interphase boundaries in an Fe-Cr ferritic steel strengthened by dispersed TiO2 particles. Pronounced interfacial Cr segregation was found to occur in the course of annealing at 700°C. The Cr segregation also leads to Cr diffusion into the dispersoids and to the formation of oxide phases with different Cr/Ti ratios. The observed Cr segregation is described in terms of diffusion into the field of elastic stresses.
