Lecture
This lecture covers some basic facts about intermetallic compounds, including their formation, classes, and properties. It discusses the Laves phases, Hume-Rothery phases, ordered phases with superstructure, IMCs with CsCl structure, Zintl phases, and closed packed phases. The lecture also explores the Hägg phases, criteria for solid solutions formation, disadvantages of intermetallics, reasons for brittleness, and potential applications in various industries. Additionally, it delves into specific examples like titanium aluminides, nickel aluminides, and iron aluminides, highlighting their properties, strengthening mechanisms, mechanical performance, and creep behavior.
