ATOMIC DIFFUSION CONTROL DURING TEMPERING OF STEEL 20Cr11MoVNbNB

Abstract

Abstract: Studies were made of the effect of tempering at temperatures from 25 to 750℃ for 0.5 to 100 h on changes of hardness,precipitated phase and its alloying element content as well as activation energy of tempering for quenched steel 20Cr11MoVNbNB.Tempering of the steel at temperatures below 400℃ may be controlled by the diffusion of C atoms in α-Fe,and above 400℃,by diffusion of Cr,also Mo or V,in α-Fe.

Key words: steel 20Cr11MoVNbNB, tempering, precipitate, activation energy
