Prof. Alexopoulos Nikolaos, University of the Aegean, Greece
Dr.-Eng. Nikolaos Alexopoulos received his Ph.D. (2004) in Mechanical Engineering and Aeronautics from the University of Patras, Greece. His Doctoral research focused on the development of a methodology to evaluate the quality of cast aluminium alloys for aeronautical applications by linking microstructural characteristics with mechanical properties. He conducted Post-Doctoral research (2005-2007) at the National Technical University of Athens (NTUA), Greece regarding the structural integrity degradation of aeronautical aluminum alloys and structures due to corrosion funded by the Greek State Scholarships Foundation (Ι.Κ.Υ.). He has been a Research Associate at the Research and Development Department of Hellenic Aerospace Industry (HAI) (2007 to 2010) gaining valuable Industrial experience. In 2012 he was elected at the University of the Aegean where he still serves as Assistant Professor of Mechanics of Materials. Research interests of Dr. Alexopoulos lies within the sector of experimental mechanics, mechanical behavior of engineering materials, fracture mechanics, casting of aluminum alloys, corrosion of aluminum alloys and steels, nanomaterials and nanocomposites. He has published more than 50 papers in scientific journals, presented more than 100 papers in conference proceedings and currently has a Hirsch-index = 17. He has participated in more than 20 National and European research projects; while he is an elected member of Board of Directors of the Greek Society of Experimental Mechanics of Materials (GSEMM) as well as of the EURopean ASsociation for Experimental Mechanics (EURASEM).
Plenary talk: “Progress in Solid State Joining of Metals and Alloys”
Øystein Grong (born in 1956), received his PhD degree from the Norwegian University of Science and Technology (NTNU) in 1983. He has worked as a Research Scientist at the Norwegian Defence Research Establishment, Kjeller, Norway and as a Visiting Research Professor at Colorado School of Mines, Golden, Colorado and National Institute of Standards and Technology, Boulder, Colorado (USA). He was appointed Professor of Metallurgy at the Norwegian University of Science and Technology in 1987 by the King of Norway and the Prime Minister. Professor Grong has a broad interest and research experience in materials in general and microstructural modelling in particular. A significant part of this work is related to thermomechanical processing and welding of metals and alloys. He has educated 58 MSc and 22 PhD students and written 264 publications, including 94 major scientific papers in referred international journals. He is also the author of the well-reputed textbook Metallurgical Modelling of Welding, which formerly was ranked among the top ten books (best sellers) from the Institute of Materials in London. In addition, he holds seven patents and has received four international awards and one prestigious national award for his scientific contributions. Professor Grong is currently self-employed through his own company and fully engaged in the development of the Hybrid Metal Extrusion & Bonding (HYB) process together with industry partners and colleagues at the Department of Mechanical and Industrial Engineering, NTNU.
