| Abstract Scope |
High-speed steels are steels alloyed with certain elements to achieve high hardness and wear resistance, both at room and elevated temperatures, for the manufacture of cutting tools. The aim is to explore an unconventional route for efficient heat treatment and compare the microstructure of M35 HSS steel under conventional conditions. The heat treatments were carried out using two routes: 1) a conventional route, laboratory muffles, and oil quenching, and 2) an unconventional route using a Joule heating device and forced air quenching. The thermal cycle was divided into two stages: a quenching stage and contiguous tempering stages, ensuring the decomposition of retained austenite and carbide precipitation. The resulting microstructure of both routes was analyzed and compared using scanning electron microscopy, X-ray diffraction, and Vickers microhardness. It was demonstrated that the unconventional route is more efficient in terms of time, obtaining similar results in terms of microstructure and microhardness. |
