Hugh J. McQueen is professor emeritus of materials and manufacturing in mechanical engineering at Concordia University and has served one term as the department chair. Since 1965, he has been conducting hot working research in industrial alloys of Al, Cu, Ni and Fe with special emphases on Al alloys and composites and on stainless steels. He has broadened his experience with sabbatical leaves at Comalco and BHP Research Centers (Melbourne), Norwegian Institute for Technology (Trondheim), Universities of Ancona, Erlangen-Nurnberg and Hamburg-Harburg. Professor McQueen also has taught undergraduate and graduate courses in mechanical properties and forming technology and has produced a short film on Dislocations. Before coming to Concordia in 1968, he had conducted research at CANMET and been associate professor at Ecole Polytechnique, Montreal. In 1961, he obtained his Ph.D. in Metallurgy from Notre Dame University (Indiana), following a B.Eng from McGill University in 1956 and a B.Sc from Loyola of Montreal in 1954. He is a fellow of Canadian Institute of Metallurgy, the Institute of Metals, Materials and Minerals the American Society for Metals and of the Canadian Society for Mechanical Engineering. In 2000, he received the Alcan Award in recognition of research and education contributions. From 1986 to 1998, Dr. McQueen served the Metallurgical Society CIM as a member of the Board and as chairs of the Microstructural Science Section and of the Metal Fabrication Section. He organized the International Conference on Strength of Metals and Alloys in Montreal in 1985 and served on its advisory council.

Prof. Stefano Spigarelli has been a professor of metallurgy on the engineering faculty at Universit¿olitecnica delle Marche, Ancona, Italy, since April 2005. His research activity is mainly focused on the high-temperature mechanical properties of light metals and steels. His current interests include creep and hot w
