Abstract

The parameters hardness, yield strength, ultimate tensile strength, toughness and Young's modulus of carbon steel C45E, EN 10083 (AISI 1045) annealed, quenched and tempered at various temperatures have been determined. Young's modulus has also been measured from ultrasonic techniques and also from the tension test; elastic deformation has been determined by the electric gaugue method. A metallographic study by scanning electron microscopy has also been carried out to confirm the results of the thermal treatment. Hardness, yield strength and ultimate tensile strength increases as it is with the thermal treatment. In addition Young=s modulus increases from 199-200 GPa (quenched) state to 211-212 GPa (tempered 500 °C, 1 h.). The annealed steel presents a Young's modulus of 206-207 GPa. A good agreement between Young's modulus values obtained by ultrasonic measurements and by tension test has been observed. This behaviour has been correlated with the distribution of dislocations in the material under the various states.
