Özet

In the present study, the tensile properties of three microalloyed medium carbon steels, containing different amount of vanadium, were investigated in the temperature range of 25-400 degreesC at a strain rate of 1.2 x 10(-3) s(-1). Both microstructure and fracture surfaces were examined using optical and scanning electron microscopic (SEM) techniques. The three steels displayed different tensile behavior at elevated temperatures and these differences are discussed with regard to the chemical compositions and fracture surface morphology.
