Professor Dahle obtained his MEng and PhD in Metallurgy from the Norwegian University of Science and Technology in Trondheim, Norway. His PhD was supervised by Professor Lars Arnberg, and was on solidification and mushy zone behaviour of aluminium alloys. He received an honorary doctorate in 2010.
From 1997 to 2012, Dr Dahle was a Professor in the Division of Materials in the School of Engineering at the University of Queensland in Brisbane, Australia.
Professor Dahle joined Jonkoping University in September 2013
Dr Dahle’s research is in the area of physical metallurgy of light alloys, with particular focus on solidification processing of light alloys, rheology of the mushy zone, casting defect formation, microstructural evolution and control, grain refinement and eutectic modification. His current research projects in light alloys include (i) development of high integrity Al alloys; (ii) eutectic modification of Al-Si alloys, (iii) grain refinement of Mg alloys; (iv) rheology of partially solid light alloys; (v) casting defect formation in light alloys and (vi) layered composite structures. Much of the research has been conducted with support and collaboration with local and international companies.
Professor Dahle has more than 250 publications, with 150 publications listed on Web of Science and a h-index of 27. He is also the creator of revolutionary hydrogen storage technology which is being commercialised by spin-off company Hydrexia in Australia. Dr Dahle has 5 patents.
He has won several awards for his research and teaching, including becoming Best Teacher at The University of Queensland in 2011.
