Title: Equilibrium grain boundary segregation of phosphorus in 2. 6Cr-0. 7Mo-0. 3V steels

Abstract

The equilibrium grain boundary segregation of phosphorus in two 2.6Cr-0.7Mo-0.3V steels with 0.06 and 0.005 Wt% of C tempered at 823, 853 and 913 K was investigated. Auger electron spectroscopy was used to establish the grain boundary concentrations of the P, C, Cr, Mo and V. Chemical compositions of the carbides were determined by means of EDX/STEM. The standard McLean's theory and Guttmann's theory of co-segregation were used to analyze the experimental data. The values of [Delta]H[sub P], [Delta]H[sub Mo], [Delta]G[sub P][sup 0], Delta G[sub Mo][sup 0], and [alpha][sub MoP] were calculated. The value of interaction coefficient calculated according to Guttmann's theory is low to suppose the influence of molybdenum upon the P segregation. The more expressive changes in the grain boundary concentrations of P and C in relation in tempering temperature were found out in the steel with lower C content.
