This lecture provides an introduction to metallurgy, focusing on the production, design, and optimization of metallic alloys for technological applications. It serves as a foundational course for understanding the scientific principles of metallurgy, emphasizing practical aspects. The lecture covers three main alloy systems: aluminum, copper, and iron, while also discussing general principles applicable to all alloys. Key topics include the historical context of metallurgy, the extraction processes of metals, and the development of microstructures. The course structure includes three hours of lectures per week, supplemented by exercises and practical work. Students will engage with various resources, including a course booklet available on Moodle, and will be assessed through written examinations. The lecture aims to motivate students for advanced studies in metallurgy and related fields, providing a comprehensive overview of the subject matter.
