Scope

This symposium focuses on the critical role of tramp elements in recycled and scrap-based metallic systems and their implications for sustainable manufacturing. As global demand for circular materials usage intensifies, increased reliance on scrap feedstocks introduces challenges associated with residual elements such as Cu, Sn, Ni, Pb, and others that are difficult to remove during conventional processing. These elements can significantly influence phase stability, microstructural evolution, defect formation, and ultimately mechanical and functional performance.

The symposium aims to bring together researchers and industry practitioners to address fundamental and applied aspects of tramp element behavior across a range of alloy systems, including ferrous, non-ferrous, and high-performance alloys.

Topics of interest include:

Advanced characterization of trace elements
Thermodynamic and kinetic modeling of impurity effects
Impacts on casting, forming, and additive manufacturing
Impurity mitigation, tolerance design, and alloy innovation
Industrial challenges and impacts on processing, microstructure, and performance

By integrating insights from characterization, processing, and modeling, this symposium will provide a platform to advance the scientific understanding and practical solutions needed to enable robust, high-quality manufacturing from recycled materials, supporting the transition toward a more sustainable and resource-efficient materials economy.
