Two fresh research papers on high entropy alloy (HEA) corrosion behavior have been published in the Corrosion Science and Journal of Alloys and Compounds. The two papers discuss the degradation mechanisms of a newly synthesized HEA, and are products of a recent collaborations between National Corrosion and Materials Reliability Laboratory (NCMRL) and the Ocean Engineering Department of Texas A&M University.
HEAs are advanced alloys that have been recently discovered that contain five or more principal elements in certain ratios. The wide ranges of compositions and microstructures make them exhibit certain exceptional mechanical properties. This makes them a key in shaping the future of material design and manufacturing. When designing a new HEA, one of the main considerations is whether it can work in various environments, or if it shows excellent corrosion resistance. However, it’s usually not that straightforward. In order to advance the understanding of the corrosion behavior of HEAs, researchers at Texas A&M University are collaborating to bring new insights to fully tackle those questions.
These two new papers are the most recent effort of NCMRL to improve the competitiveness of US in advanced manufacturing. Currently, NCMRL is also implementing new research in discerning the corrosion behavior of 3D-printed metals and developing new testing methods and standards for this novel manufacture approach.
