Håkon Longva Korsvold started as a PhD candidate at SFI PhysMet in August 2023. The topic of his PhD project is Advanced nanoscale characterization of grain boundary segregation in metals. Håkon will study segregation of solute atoms to grain boundaries in aluminium alloys using state-of-the-art characterization techniques. Solute atoms are known to influence grain boundary behavior and to affect properties such as strength, corrosion and recyclability.
Samples of grain boundaries will be created using focused ion beam microscopy (FIB), these samples will then be studied using atom probe tomography (APT) and transmission electron microscopy (TEM).
We have asked all the PhD candidates what they believe will be the impact for industry of their project. The aim of Håkon's project is to increase our understanding of the effect of solute grain boundary segregation, aiding in alloy design and recyclability. Experimental data can be used to validate and develop atomic scale simulations for alloy design.
Before he started as a PhD cancidate Håkon finished his Master’s degree in Nanotechnology at NTNU. The topic of his master thesis was TEM studies of precipitates in HYB welded Al-Mg-Si-Cu.
