| Abstract Scope |
The emergence of compositionally-complex alloys (CCAs) as a new frontier of corrosion-resistant alloys has opened doors for advanced optimization of the usage of corrosion-resistant elements for promoting passivation of each phase and self-healing. However, researchers must contend with a design space with vast compositional and microstructural possibilities, and a literature base focused primarily on one-off alloy development. In this work, a methodology for the rapid (~1 alloy/second) discovery of alloy compositions possessing the desired phase stability using the CALPHAD approach is presented. This approach utilizes equilibrium information regarding a specific composition such as its solidus temperature to maximize the probability of discovering an alloy with a disordered matrix-(or single-)phase microstructure. Further, a set of alloys with common Co-free FCC elements (FexNiy)80Cr10(AlaSibTic)10 was designed using this tool to further explore and define the specific impacts of light weighting elements Al, Si, Ti have on corrosion performance in a single-phase microstructure. |
