EXPERIMENTAL INVESTIGATION OF THE MECHANICAL AND MICROSTRUCTURE PROPERTIES OF S49 RAIL STEEL

Abstract

This study was carried out to determine the microstructure and mechanical properties of S49 rail steel. For this purpose, firstly, three samples of S49 rail steel material were prepared by cutting by wire erosion method for three point bending test. Microstructural analyzes of S49 rail steel were examined by scanning electron microscopy (SEM). Energy dispersion spectrometer (EDS) analysis was performed to determine the chemical composition of the S49 rail steel material. Hardness test and three point bending test were performed to determine the mechanical properties of the samples. SEM and EDS analyzes of fractured surfaces were performed from the broken samples after the three point bending test.
