The detailed study through microstructural observation on the initial stage of precipitation behavior of the Laves phase in the 9--12%Cr ferritic steels is slightly difficult, because the matrix phase is martensite containing a high number density of dislocations and, secondly, the similar size and shape of carbides are formed with the Laves phase during aging treatments. In the present research, the precipitation behavior of the Laves phase, particularly, focusing on an initial stage of it, was investigated using sample Fe-10%Cr ferritic alloys.
