   Abstract : This master thesis presents a theoretical investigation of the energy and stability of interfaces in iron-carbide compounds, specifically focusing on the α-Fe/Cr7C3 system. The study aims to fill the gap in knowledge regarding the surface energetics of these interfaces using Density Functional Theory (DFT). READ MORE

3. 2. Examination of defects and long term crack growth in rolled bars during long term storage

   University essay from KTH/Materialvetenskap

   Author : Jon Scheutz; [2014]
   Keywords : Rolled bars; cracking; hydrogen damage; long term storage;

   Abstract : This work has had the purpose to examine defects and the cause of crack growth during long term storage in rolled bars. The bars in question are rolled and stored at Ovako in Hofors. The problem is approached by theoretically examining the possibilities of hydrogen damage, room temperature creep and naturally occurring porosity. READ MORE
