The global shift toward sustainable manufacturing necessitates innovative qualification and standardization approaches for alloys that utilize increased scrap content. As scrap utilization rises, managing the increasing impurity levels, such as increased copper (Cu) content in steel alloys has become increasingly important. This presentation presents a framework for the design of impurity-tolerant steel alloys using CALPHAD-based simulations. 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, as well as identifying critical data and standard needs. |
