Lecture
This lecture covers the fundamentals of metallurgy, including topics such as world reserves of metals, shaping processes for automotive parts, structural hardening heat treatments, and the toughness of metals and alloys. It also delves into the TTT diagram of low carbon steel, heat treatments, and the hardening mechanisms of metals. The instructor discusses the properties of steel, the hardening mechanisms, and the classification of iron alloys. Additionally, the lecture explores the hardenability of steels, surface treatments, and the great families of steel, providing insights into the composition and mechanical properties of different types of steel.
