Abstract
The pursuit of continuous improvement of product design and processes in the different fields of engineering and technology has brought about significant changes in the manufacturing industry, driven by the improvement in the mechanical and tribological performance of new materials. For example, cutting tools need to withstand increasing loads and be equally resistant to wear. However, materials naturally available to man need structural adaptation so that these properties can interact. Applying thermal treatments to engineering materials has contributed to better tool lifespan by achieving greater mechanical resistance to wear. In particular, as milling is concerned, the AISI M2 fast steel is widely used as a cutting tool, also to forming prossesses and tool shop in general. In order for the AISI M2 to sustain high mechanical resistance at high temperatures, a series of thermal treatments are quite necessary. This work proposes to assess, using statistical methods, the effect of thermal treatments and structural changes on surface hardness and wear resistance of AISI M2 fast steel. In this study, a group of annealed, tempered and drawtempered commercially available test specimens were used.
