Prof. Dr. Frank Walther studied Mechanical Engineering, majoring in Materials Science and Engineering at TU Kaiserslautern University, Germany, where he completed his PhD on the fatigue assessment of railway wheel steels in 2002 and his habilitation on the metrological acquisition of microstructure and fatigue evolution of metals in 2007. From 2008 to 2010 he was a member of Corporate Innovation and Knowledge Management and Corporate Engineering at Schaeffler Technologies in Herzogenaurach, Germany, and since 2010 he has been a Professor of Materials Test Engineering (WPT) at TU Dortmund University, Germany. His main research focuses on the microstructure-based characterization and modeling of fatigue behavior depending on production and service, aiming at a comprehensive process–structure–property understanding. He maintains close scientific contact with institutions and industries worldwide.
