| Abstract Scope |
High-speed steels (HSS) are used to manufacture cutting tools due to their high hardness and wear resistance, both at room and elevated temperatures. The aim is to characterize and compare the microstructure of an M35 HSS steel under quenched and tempered conditions. The steel was thermally processed using two treatment routes: 1) a conventional route, laboratory muffles, and oil quenching, and 2) an unconventional route using a Joule heating device and forced air quenching under the same heat treatment temperatures. The thermal cycle consists of two stages: a quenching stage and a series of contiguous tempering stages to ensure the decomposition of retained austenite. The resulting microstructure of both routes was compared using scanning electron microscopy, X-ray diffraction, and Vickers microhardness measurements. Finally, it was demonstrated that the unconventional route is more efficient concerning treatment times, obtaining very similar results in terms of microstructure and microhardness. |
