Using multiple advanced characterisation techniques - the rolling contact fatigue case
Hear Tania Loaiza Uribe defending her PhD thesis - and gain an insight into how to use a range of advanced characterisation techniques to investigate different aspects of material behaviours
Time: Fri 2024-02-09 10.00
Location: Kollegiesalen, Brinellvägen 8, Stockholm
Tania Loaiza Uribe is defending her PhD thesis "Microstructural Decay Investigation of High-Strength Bearing Steels under Rolling Contact Fatigue" on 9 February from 10am in Kollegiesalen, Brinellvägen 8, Stockholm.
Tania identified the mechanisms leading to rolling contact fatigue in different types of steels. Her work should contribute to improving ball-bearing performance in applications such as wind turbines and electric vehicles.
In addition to measurements at the PETRA III Swedish Materials Science beamline, Tania identified the mechanism leading to fatigue by using a wide range of advanced characterisation techniques at the Hultgren Laboratory. These include Scanning Electron Microscopy, Electron Backscatter Diffraction, Focused Ion Beam and Transmission electron microscopy, Atom Probe Tomography, Nano-Indentation, Micro-Hardness and micropillar compression.
The PhD thesis has been conducted in collaboration with Ovako Group within the MMD centre at KTH Royal Institute of Technology.
Supervisors: Prof. Peter Hedström, Dr. Prasath Babu Revathy Rajan, Prof. Mårten Olsson (KTH Royal Institute of Technology)
Opponent: Prof. Sir Harshad 'Harry' Bhadeshia (Queen Mary University of London)
Evaluation Committee: Prof. Johan Moverare (Linköping University), Prof. Uta Klement (Chalmers University of Technology) and Dr. Erik Vegter (SKF Group).
Chair of session: Prof. Annika Borgenstam, KTH
