| Abstract Scope |
The demand for more sustainable alloys and processes requires a new element in the well-defined processing-structure-property-performance systems approach. As the design process is always a balancing of various conflicting objectives, several key challenges in incorporating sustainability and recyclability into the design process are considered. What are the available tools to evaluate different processes methods and end-life recyclability of the designed material? What tools are needed to evaluate available scrap materials that may reduce cost, energy consumption, and emissions? How can the amount of scrap material be increased in the primary alloy content without impacting the desired performance? How does one identify critical materials and design for replacement alloying elements? Much of the infrastructure required to meet these new challenges have been developed through the Materials Genome Initiative. Some examples of the tools available to meet these challenges are applied to different Al, steel, and superalloy designs. |
