Metallurgical methods for the production of steels with high manganese contents [Metallurgische verfahren zur herstellung von stählen mit hohen mangangehalten]

• Ferrous alloys using the TRIP and/or TWIP effect allow a combination of ultra-high strength and high ductility. The alloying concepts for theses steels are based on a manganese content between 12 and 25 % mass content. Other alloying components typically are aluminium and silicon. The presented research focusses on the assessment of economically viable process routes for the production of high manganese-content steel melts. Routes for mid- to long-term high production volume using iron-manganese-ores in a blast furnace or for direct reduction are presented. Being crucial for profitability different manganese sources and alloying concepts are discussed and evaluated under the aspect of tramp elements.
