| Abstract | Herein, it was studied the structural evolution of the AISI 1045 steel water-quenched and oilquenched, respectively, from a temperature higher than the critical to various temperatures between 800 and820 C. The two quenching media were used at 16.5 C. Microstructural variations occurred in the quenched 1045 steel. Also, by using the four-terminal sensing, it was measured the evolution of the electricalresistivity of the quenched samples; it was found that quenching at different temperatures provoked a complex behavior. It was noticed a major increase in the electrical resistivity in the case of water-quenched samples. Besides, when compared samples before and after being heat-treated, via a metallographic analysis, it was showed an evolution of the phases of steel, what has a link with the evolution of the electrical resistivity, which was measured according to the increase of the austenitizing temperature. |
