Abstract: The depleted and enriched regions of solute atoms formed by spinodal decomposition in the early stage of tempering for ultrahigh strength steel 23Co14Ni12Cr3 were first confirmed by means of transmission electron microscopy (TEM). The segregation of solute atoms provides favorable composition and structure fluctuationfor the formation of secondary hardening phase M2C and cementite Fe3C.
