The high-speed steel Z80WCV 18-04-01 is highly valued in intensive machining for its exceptional characteristics such as high hardness and heat resistance. Composed of carbon, chromium, tungsten, and vanadium, this steel is particularly suitable for manufacturing cutting tools such as lathe tools, milling cutters, drills, and taps. The cumulative tempering process plays a crucial role in enhancing these properties, directly influencing the performance and durability of turning tools. This research aims to evaluate the effects of different tempering treatments on Z80WCV 18-04-01 high-speed steel turning tools, focusing on hardness, toughness, and microstructural changes, tempering involves heating the steel to a specific temperature below its critical point and then cooling it, which modifies its internal structure to achieve desired mechanical properties. By varying the tempering temperature and duration, researchers can tailor the steel's hardness and toughness to optimize performance in cutting applications. Understanding these changes is essential for developing tools that can withstand the demanding conditions of industrial machining processes, the microstructural analysis will provide insights into how the steel's grain size, carbide distribution, and phase composition evolve with different tempering treatments.
