Intermetallics: Borides, Carbides, Nitrides

This lecture covers the crystallographic structures and stability of intermetallic compounds such as borides, carbides, and nitrides, with a focus on the concept of Hägg-phases. It discusses the characteristics of different types of borides, the crystal structures of borides, and the formation of transition metal carbides. The lecture also explores the thermal and chemical stability of carbides, the formation of Hägg-phases, and the role of carbides in steel and HSLA steels. Additionally, it delves into the formation of stable carbides and nitrides in various metal groups, highlighting their solubility and stability.
