“…They are rarely used for metal and alloys cutting, since they are rapidly overtempered at moderately low cutting temperature. These types of steels contain about 0.6-1.5% of C and small quantities of Si, Cr, Mn, and V. In 1868, Robert Forester Mushet discovered that the hardness of steel can be enhanced by addition of W [6] and it was the starting point for the discovering of high speed steels (HSSs) [7] indispensable in case of high cutting speeds (this is the reason they are called high speed steels) and increased temperature. The addition of alloying elements to harden and strengthen the basic material and to obtain a more resistant one in extreme conditions makes the difference between CS and HSS [8].…”

Among other materials, hard metals represent an important family of functional materials. They show properties that are combinations of those of their constituents. The general idea while using hard metals is to exploit their excellent properties in terms of hardness, toughness, wear resistance, and chemical stability. These characteristics made hard metals as promising candidate for use as a cutting tool, which constitutes their main area of application. Depending on the particular use, the most important properties can be achieved: (i) by properly selecting the constituents made up the whole composition, (ii) by varying the relative composition of the phases, or (iii) by applying a suitable hard metal coating layer on the top of the cutting tool. This chapter presents a general overview of the actual scenario concerning different tool materials, including a short history and description of state-of-the-art techniques as regards their composition, their manufacturing routes and their most important properties. Some results of the own research in this field are carried out during the years will integrate this part.

“…Hard materials consisted of hard phases and binder phases. The hard phases provided the properties of high strength, hardness and wear resistance, while the binder phases provided the necessary toughness for the material deformation 5,6) . So far the metal-carbides, -nitrides and -borides were commonly used as hard phases 7) .…”

“…A broad range of WC grades with different particle sizes and the addition of various types of carbides to WC have been investigated to improve the mechanical properties of WC-Co hard materials 4) . However, the application of such hard materials has been limited due to the low reserves and poor re ning ef ciency of W. Simultaneously, Co is low reserves and expensive 5) .…”
