Abstract

In ultrahigh-strength (UHS) steels, the gettering of the elements responsible for intergranular stress-corrosion cracking (SCC), such as P and S, leads to significant improvement in resistance to SCC. It is possible to obtain very fine dispersion of various phases with the use of rapid solidification processing (RSP) and with the addition of various levels of La, Ti and Zr as impurity getters. The study deals with identifying various phases formed in rapidly solidified UHS steels using extraction replicas. A cold field emission Hitachi HF2000 atomic resolution analytical electron microscope (ARAEM) was used for phase identification. Both X-ray microanalysis and convergent beam electron diffraction were used for characterizing the phases.
