Characterization of TiO2-dispersoids in a ferritic Cr-steel by analytical electron microscopy

Project: Research area

Project Details


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