Lecture
This lecture covers the properties and applications of titanium aluminides, focusing on TiAl and TigAl phases, their ductility, and alloying with Nb. It also discusses the oxidation resistance of titanium aluminides compared to titanium alloys. Additionally, the lecture explores the similarities between zirconium and hafnium, their production processes, atomic radius, and applications in nuclear reactors. The separation processes of zirconium and hafnium due to their chemical similarities are detailed, along with the reduction of oxygen in zirconium and hafnium using the Kroll process.
