Live Event: November 3, 2022
Explore the reduction methods that are most promising and the scientific bottleneck questions that must be solved to make green steel become a reality in this new TMS Webinar. Examine existing basic research questions associated with producing steel more sustainably, particularly with lower CO2 emissions. Discuss the main research items that must be tackled to enable green steel making and to re-invent a 3,000-year-old industry within less than a decade.
More than 1.85 billion tons of steel are produced every year, making it the most important alloy in terms of volume and impact. While steel is a sustainability enabler, through lightweight car parts, wind farms, and magnets, its primary production is the opposite. Its reduction from oxides through fossil carbon carriers produces about 2t CO2/t of steel produced, qualifying it as the largest single cause of global warming.
Learn from an expert in this field and address recent progress and open issues in hydrogen-based direct reduction and hydrogen-based plasma reduction including topics such as the kinetics of the solid state and plasma-based reduction reactions, mass transport kinetics, nucleation during the multiple phase transformations, the oxide’s chemistry and microstructure, the roles of plasticity, damage, and fracture associated with the phase transformation, and mass transport phenomena occurring during and possible simulation approaches.
What You Will Learn
- Examine basic research for making green steel
