2. 1. Inside The Miscibility Gap : Nanostructuring and Phase Transformations in Hard Nitride Coatings

   Author : Lars Johnson; Lars Hultman; Magnus Odén; Michael Kopnarski; Linköpings universitet; []
   Keywords : ;

   Abstract : This thesis is concerned with self-organization phenomena in hard and wear resistant transition-metal nitride coatings, both during growth and during post deposition thermal annealing. The uniting physical principle in the studied systems is the immiscibility of their constituent parts, which leads, under certain conditions, to structural variations on the nanoscale. READ MORE

4. 2. Valence Electron Energy Loss Spectroscopy of III-Nitride Semiconductors

   Author : Justinas Pališaitis; Per Persson; Lars Hultman; Jens Birch; Vicki Keast; Linköpings universitet; []
   Keywords : ;

   Abstract : This doctorate thesis covers both experimental and theoretical investigations of the optical responses of the group III-nitrides (AlN, GaN, InN) and their ternary alloys. The goal of this research has been to explore the usefulness of valence electron energy loss spectroscopy (VEELS) for materials characterization of group III-nitride semiconductors at the nanoscale.

5. 3. Modelling phase separation in Fe-Cr alloys : A continuum approach

   Author : Thomas Barkar; John Ågren; Nele Moelans; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Phase separation; spinodal decomposition; nucleation; diffusion; thermodynamics; kinetics; steel; ferritic;

   Abstract : The formation of Cr-rich and Fe-rich domains upon ageing of an initially homogeneous Fe-Cr alloy at elevated temperatures (300-600 ºC) is commonly referred to as phase separation. The behaviour originates from a miscibility gap in the Fe-Cr phase diagram. READ MORE
