About me in general:
I grew up in a small town in the southern part of Denmark. During my last year at high school I was participating in a project between the school and the local industry. I ended up spending two weeks at a Hydro Aluminium plant where I discovered “the magic universe” of metals. In 2002 I moved to Trondheim and commenced my Masters in Materials Science and Engineering. Finished my Masters spring 2007 and started as a PhD candidate at SIMLab in September 2007.
Subject of my PhD:
Work- and age-hardening of 7xxx aluminium alloys
The objective of my work is to gain knowledge about the work- and age hardening mechanisms in heat treatable aluminium alloys by use of metallurgical characterization of the material subjected to typical industrial artificial ageing. The experimental data is to be used for validation and further development of already existing models for predicting microstructure and mechanical properties.
The experimental work will be limited to the 7xxx alloying series where four representative industrial 7xxx alloys have been chosen. Plastically deformed materials such as extruded profiles are usually affected by texture due to the forming process, i.e. the material becomes anisotropic. To elude this effect the experimental study will at first be based on as-cast material to investigate the relationship between precipitation and mechanical properties. Later on extruded profiles will also be a part of the study to understand the effect of work hardening on the precipitation kinetics.
