Morten Karlsen
About
I am Professor 2 at the institute, and employed in Equinor.
My competence area covers steel for onshore and offshore applications in the energy sector (oil, gas and renewables). My core competence is within materials charcterization, an din particular the use on EBSD in SEM.
I teach the course TMT4242 Steel Offshore.
In 2009 I was the winner of the Cook/Ablett Award for published work of particular merit in the field of metals for the article “SEM/EBSD based in-situ studies of deformation-induced phase transformations in supermartensitic stainless steels”. The article was published in Materials Science and Technology 2008 vol. 24 no. 1.
