Biography

Material based steel research for implementing future manufacturing technologies in commercial application. Research is focusing mainly on 1) tailoring material properties using novel heat treatments and 2) manufacturing of advanced products using new materials and manufacturing methods, such as metal additive manufacturing.

1) Novel heat treatments: Combinations of fast and ultra-fast annealing technologies with various deformation methods such as cold rolling or shot peening. The study aims for enhancing the material properties of final products, but also to reduce environmental load of the manufacturing processes.

2) Advanced steel products: The research question is how to utilize the good material properties of steel into good properties of the final products. Comparison is made especially between additively manufactured parts and conventional methods. In additive manufacturing, the research has a strong focus on predicting and optimizing the fatigue strength of the manufactured parts.
