SEMINAR Structure-property relationships of advanced metallic materials
PRESENTER Dr. Sophie Primig WHERE BLD 8.114 DATE Thursday 5th of May 2016 TIME 3.00pm -4.00pm
ABSTRACT Advanced metallic materials can be designed to meet current challenges in structural applications such as engineering and construction, automotive applications, aviation and aerospace, medical technology, and electronics. Their outstanding properties such as high (hot) hardness and strength, high toughness, low specific density, or high corrosion resistance are determined by their microstructure after processing. I will present some results of recent projects that showcase my research in microstructure-property relationships of advanced metallic materials with both scientific focus and industrial impact. These include the B2 order transformation in a novel Fe-25 at% Co-9 at% Mo cutting material and its influence on the mechanical properties, correlative microscopy of the martensite-austenite constituent in a carbide-free bainitic automotive steel, an approach to increase the precipitation potential of the molybdenum-based alloy MHC (Mo-Hf-C), and comprehensive chemical and crystallographic characterisation of grain boundary segregation by applying focused ion beam microscopy, transmission Kikuchi diffraction and
ABOUT THE SPEAKER I was awarded both my Ph.D. in Mining and Metallurgical studies (July 2012) and my Master in Materials Science (November 2008) degrees at the Montanuniversität Leoben, Austria. My Ph.D. research was carried out in the Department of Physical Metallurgy and Materials Testing under the supervision of Prof. Helmut Clemens and was an applied project in collaboration with Plansee SE, Austria. I designed and oversaw the metallurgical implementation of a new rolling and annealing schedule for the production of defect-free molybdenum plates such as are required for various electronics, coatings and high temperature structural applications. During my Ph.D., I was fortunate to receive additional funding to conduct thermal analysis studies to investigate precipitation mechanisms in steels under the auspices of Austria's Christian Doppler Society in the framework of the Christian Doppler Laboratory Early Stages of Precipitation. I was appointed to the position of a Post-Doctoral research fellow in the Christian Doppler Laboratory after finishing my Ph.D. research. During this time I extended my research portfolio to new materials and methods such as nickel-based alloys and grain boundary segregation. In July 2013, I successfully applied for a continuing position as "Senior Scientist" at the Montanuniversität Leoben where I headed the "High Performance Materials and Steels" research group for two years and established a strong network with European industrial partners. In July 2015 I moved to the opposite side of the globe seeking new challenges as lecturer of physical metallurgy at the School of Materials Science & Engineering, UNSW Australia.
