SUSTAINABILITY WEBINAR SERIES
CALPHAD-based Strategies for Integrating Sustainability into Alloy Design
Speaker: Dr. Carelyn Campbell
Tuesday, November 18, 2025 at 3 PM CET/9 AM EST
The escalating demand for sustainable alloys and processes necessitates innovative design and optimization approaches, including increased scrap utilization, reduced energy-intensive processing, and enhanced service lifetimes.
This webinar will highlight a few CALPHAD-based strategies for incorporating sustainability into the design of more impurity tolerant sheet steel. Specifically, how to best optimize the HSLA 340 cold-rolled steel to accommodate the rising Cu impurity content in the current scrap supply. CALPHAD-based simulations will evaluate how copper increases hot-cracking and crack-susceptibility, and impacts solidification and continuous cooling microstructure evolution, thereby affecting critical material properties like ductility and formability.
Based on these evaluations, potential strategies are considered to compensate for detrimental properties due to increased copper content. These include optimizing cooling rates and aging temperatures, re-optimizing alloying elements to increase precipitation strengthening, and potential alloying additions to improve grain boundary adhesion. This example provides a framework for developing more robust and sustainable alloys in the face of evolving material demands.
