Steel in Translation Aims and scope

Abstract

A method has been developed for quantifying the proportion of acicular bainite in structural steel 44Kh2G2S2MF using polarized light. The method refers to the digital direction in metallography and differs from the known analogue in that a combination of crossed nicols and rotation of the test sample around its axis is used to fully identify and accurately quantify bainite in polarized light. The dependence of the brightness level of bainite components on the detection angle of bainite in polarized light has been established, which made it possible to determine the minimum number of necessary images of the structure, which differ in the detection angle of bainite by 45°, to estimate the proportion of bainite in steel 44Kh2G2S2MF.
