    Abstract : In recent years intermetallic compounds have attracted a great deal of attention as structural materials. Among the intermetallics, gamma titanium aluminides (.gamma.-TiAl) are considered to be closest to application. READ MORE

  7. 5. Mechanical and thermal stability of hard nitride coatings

    Author : Yu-Hsiang Chen; Magnus Odén; Lina Rogström; Tomasz Liskiewicz; Linköpings universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : Hard coating’s thermal stability is essential due to the high temperature environment of high-speed cutting applications, while the phase and microstructure evolution induced by exposing the coating to high temperature affects the mechanical properties. In this thesis, the mechanical stability of arc-evaporated, hard, transition metal nitride coatings annealed at high temperature is analyzed and related to the phase and microstructure evolution.
