A detailed study of the microstructure at the site of the alleged defects of the macrostructure is performed. The main metallographic features and characteristics are shown, in the presence of which features of macro and microstructure can be classified as defects of the macrostructure. It is recommended for the control of the macrostructure of railway wheels, bandages, wheel centers in contradictory cases to perform: - additional macroscopic analysis by the Bauman method (removing the sulfur ink); - microscopic analysis of the samples according to the places of the alleged defect; - determination of mechanical properties Product Description popup.authors Бабаченко О.І.
