معرفی
Lina Rogström is an Associate Professor and Docent at Linköping University, affiliated with the Department of Physics, Chemistry and Biology (IFM) within the Faculty of Science and Engineering. She is actively involved in advanced materials research, particularly through collaborations with MAX IV Laboratory and participation in the FunMat-II and Nanostructured Materials (NANO) research environments.
Research Interests: Her work focuses on the development and characterization of hard, wear-resistant coatings for industrial cutting tools. These coatings, typically 1–10 µm thick, are crucial for enhancing tool longevity and performance under extreme conditions of temperature and pressure during metal machining. She investigates the structural and mechanical behavior of coatings such as TiAlN and AlTiN under operational conditions, aiming to reduce reliance on cooling fluids and enable higher cutting speeds.
To achieve this, she employs a multidisciplinary approach combining experimental techniques like in-situ synchrotron X-ray diffraction, high-energy XRD, XANES, and EXAFS to study phase evolution, stress development, and microstructural changes in real time during machining or high-temperature exposure. This enables a deeper understanding of coating degradation mechanisms and guides the design of next-generation materials.
Publication Trends: Her recent publications (2023–2024) reflect a strong focus on in-operando and in-situ characterization of nitride-based thin films. These studies, published in high-impact journals like Acta Materialia and Physical Review Materials, reveal detailed insights into phase stability, age hardening, texture evolution, and strain development under thermal and mechanical loads. The research bridges fundamental materials science with industrial applications in manufacturing.
