| Abstract Scope |
Their potential to achieve high strength, excellent corrosion resistance, good irradiation resistance, and many other desirable properties makes multi-principal element alloys (MPEAs) some of modern science’s most researched materials. Most researched materials contain a large amount of cobalt. While cobalt content in MPAs is known to improve mechanical properties and can help to tailor many physical properties, its use creates questions surrounding sustainability and supply criticality. Cobalt is a key material in the production of batteries and magnets for the world’s growing electrification needs while also undesirable because of toxicity and high price instability. Thus, its use in MPEAs places additional constraints on the supply of this critical metal. This presentation will focus on numerous Co-free MPEA options which could be further tailored for specific applications. Mechanical properties, thermal stability, heat-treatment response, and microstructure studies will be presented from a suite of MPEA materials. |
