“…Temperature, Co content, and WC grain size do not have any effect on the Poisson' ratio. The highest the temperature and Co content the lowest the yield strength, while up to 700°C, Co level and WC gran dimensions do not influence significantly the fracture toughness of WCCo hard metals in accordance with other studies [48][49][50]. Above 800°C, more than 8% of Co increases considerably these properties are in good agreement with previous studies [48,51] because at this temperature the plastic zone is higher compared to the situation at room temperature and this changes the spreading of the fracture trajectory.…”

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.
