Abstract
Internal friction (IF) data show that the evolution of C-Cr_n associate distribution of MANET steel is connected to the Cr-rich carbides (M₇C₃ and M₂₃C₆) precipitation. Carbides extracted from the matrix have been investigated by X-ray diffractometry and EDS microanalysis measurements. It is discussed the hypothesis that the M₇C₃ carbides form by aggregation of C-Cr₁ associates.
