About

Pentti Karjalainen is an Emeritus Professor at the University of Oulu, Finland. His research primarily focuses on the mechanical behavior and deformation characteristics of advanced and high-performance steel alloys, with recent studies exploring topics such as austenite decomposition, strain hardening behavior, and the effects of volumetric energy density on defect structures. Additionally, he has investigated twinning mechanisms in high-entropy alloys and the formation of nanostructured surfaces during slurry erosion.
