In this master's thesis, the rich history and evolution of hard metals have been explored, highlighting their significance as materials with high mechanical properties that are indispensable across various industrial sectors. By focusing on their chemical composition, the components contributing to their unique properties and behavior under different conditions were analyzed. Microstructure, or the arrangement of microscopic components, is crucial for their performance and wear resistance. The thesis extensively examined the structural aspects of these materials to better understand their mechanical properties, wear resistance, and other key characteristics. By considering different groups of hard metals, insights into their specific properties and applications were provided, emphasizing the importance of selecting the appropriate material for each specific use. In the production segment, powder metallurgy, powder characteristics, mixing and grinding processes, as well as compacting and sintering, were described, which are essential for shaping and enhancing the properties of hard metals. The experimental part of the work focused on analyzing the microstructure of samples using the ImageJ program for precise measurement of grain size and matrix shares, providing deeper insights into the structural and functional characteristics of the materials.
