Abstract Scope |
Compositionally complex and multi-principal element alloys (MPEAs) increase the degrees of freedom in the choice of alloying elements to produce either single phase solid solutions or complex multiphase microstructures. Mastery of element selection and alloy compositions holds the hope that novel combinations of properties, unobtainable in traditional alloys, are an outcome. From the aqueous corrosion perspective, optimization of phase stability, control of ordering, heterogeneities, passive film identity and protectiveness, as well as other attributes, often govern corrosion resistance. The quest for superior properties based on well-informed choice of alloying elements within certain specified compositions is of high interest. In this presentation, the effects of combinations of Cr, Cr-Al, and Cr-Al-Ti on passivation and protection in Cantor type alloys are discussed. |
