Study of the interaction between manganese and nitrogen in Cr?Ni stainless steels by the internal friction method

Abstract

1. It was shown by experiments with four austenitic Cr−Ni stainless steels that with increasing manganese concentrations the solubility of nitrogen increases. 2. With increasing concentrations of manganese the shape of the F-R peak on the TDIF curves is distorted—broadened, transformed into a plateau, or divided into two subpeaks (for steel with 10% Mn). 3. Using the theory of pseudopotentials, we attempted to explain the anomalous form of the TDIF curves and also the character of the interaction between manganese and nitrogen atoms in austenitic Cr−Ni steels.
