Popis:	In the effort to improve the creep resistance of high-chromium ferritic steels that are candidate materials for power plant applications, additions of Nb, V, and N were found to produce wing-like vanadium carbonitrides that adhere to spherical Nb(C,N) particles during tempering. The complex carbonitrides of niobium and vanadium strongly inhibit dislocation glide during high-temperature deformation. The same type of the carbonitrides can be observed in other niobium- and vanadium-modified, high-chromium ferritic steels, and similar high-temperature, dispersion-hardening effects can be observed.
