Institut für Eisen- und Stahltechnologie

Herzlich willkommen Anton und Eldar We kickstart the second half of 2024 with two new team members, Anton Yehorov and Eldar Salpagarov. They are joining us as PhD candidates in cohort II of the Training Research Group GRK 2802, which focuses on improving raw material, energy, and climate efficiency in high-temperature processes and refractory recycling. Anton was born in Oleksandriia in 1997 and he completed his Bachelor's Degree in Materials Science at the Prydniprovska State Academy of Civil Engineering and Architecture in Dnipro. He then obtained the Dipl.-Ing title through a double degree in Materials Science with the TU Bergakademie Freiberg, specializing in steel technology. For the past two years, Anton has worked as an R&D engineer for Intocast AG. In his free time, he likes to go for a swim, usually by driving his bike and practicing kickboxing. Eldar came to the world in 1999 in the city of Tscherkessk. He acquired his Bachelor's Degree in Materials Science and Engineering at the Mining University of Saint Petersburg and his Master’s Degree in Technology and Application of Inorganic Engineering Materials at the TUBAF. When he is not hiking or reading, Eldar usually spends his time playing either computer or cardboard games. We wish both success in their careers! #TUBAF #IEST #Research #Group #Refractory #Materials #Energy #Climate #Efficiency

Metallurgiestudenten zu Freiberg e.V. on the road! From June 19th to 21st, 16 metallurgy students from the TU Bergakademie Freiberg, including our esteemed Prof. Olena Volkova, embarked on an enlightening 3-day excursion to Austria. The journey started with an insightful visit to aluminium producer AMAG Austria Metall in Ranshofen, followed by a traditional metallurgical Stammtisch in Simbach am Inn, generously hosted by the company. On the second day, the group explored the modern Voestalpine Stahlwelt museum and the renowned steel mill at voestalpine in Linz. In the evening, the metallurgy students of Montanuniversität Leoben welcomed us warmly to their summer fest in Vordernberg, creating lasting memories and forging new friendships. The excursion concluded with a visit organised by ASMET, Austrian Society for Metallurgy and Materials to the innovative stainless steel mill voestalpine Böhler in Kapfenberg, where students gained a deeper understanding of advanced manufacturing techniques. Many thanks to Metallurgiestudenten zu Freiberg e.V. for the organisation and, AMAG, voestalpine and ASMET for their incredible hospitality and for making this excursion an unforgettable learning experience! #Metallurgy #Student #Excursion #TUBAF #Montanuniversität #Leoben #AMAG #Voestalpine #Böhler #ASMET #Aluminum #Stainless #Steel

Michael Hauser, a Research Associate at our institute who has dedicated his career to advancing materials science and technology, specialising in steel metallurgy. Born in 1988 in Halle/Saale, Saxony-Anhalt, Michael's journey began early on, as he dedicated two months in 2006 to materials testing at the SLV Halle GmbH. Michael began his academic career in 2007 at the TU Bergakademie Freiberg, completing his Diploma studies in 2013, which is highlighted by an engineering internship at ArcelorMittal Bremen. His doctoral research from 2013 to 2020 focused on the thermodynamic-mechanical modelling of metastable austenitic Cr-Mn-Ni steels, contributing significantly to the SFB 799 Trip Matrix composite program. Beyond his professional accomplishments, Michael has been an active leader, serving as a board member for Metallurgiestudenten zu Freiberg e.V. In his personal life, he enjoys spending time outdoors with his children, carving, climbing, and engaging in weekly Pen&Paper gaming sessions. We are proud to have Dr.-Ing. Hauser in our team and wish him all the best in his personal and professional life. #TUBAF #IEST #Steel #Technology #SachsenAnhalt #Dr #Ing
