1. 1. High pressure and high temperature behavior of TiAlN

   Författare :Niklas Norrby; Magnus Odén; Mats Johansson Johansson; Helen Blomqvist; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : This licentiate thesis mainly reports about the behavior of arc evaporated TiAlN at high pressures and high temperatures. The extreme conditions have been obtained in metal cutting, multi anvil presses or diamond anvil cells. Several characterization techniques have been used, including x-ray diffraction and transmission electron microscopy. LÄS MER

3. 2. Microstructural evolution of TiAlN hard coatings at elevated pressures and temperatures

   Författare :Niklas Norrby; Magnus Odén; Mats Johansson; Jean-François Pierson; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : A typical hard coating on metal cutting inserts used in for example turning, milling or drilling operations is TiAlN. At elevated temperatures, TiAlN exhibits a well characterized spinodal decomposition into coherent cubic TiN and AlN rich domains, which is followed by a transformation from cubic to hexagonal AlN.
