Corrosion

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.

This week, Silas Nichols, Principal Bridge Engineer – Geotechnical at Federal Highway Administration, visited the Center for Infrastructure Renewal. Dr. Anand Puppala, Interim Director showed the CIR’s unique state-of-the-art facilities. During the facility tour, Silas was able to visit with CIR researchers and students on their work in Corrosion, Structures, and Geomaterials.

Dr. Raymundo Case provided an in-depth look at the ongoing work in the National Corrosion and Materials Reliability Lab, which focuses on solutions to the corrosion needs of industry and government in order to maximize asset life, production efficiency and worker safety. While Dr. Pete Keating showed the Structural and Materials Testing Lab’s unique ability to perform both full-scale, and also component and material testing. Prince Kumar and other members of the Geomaterials team spoke with Silas over their student research projects in the Geotechnical and Unbound Materials Innovation Lab which allows researchers to investigate soil behaviors, pavement geomaterials, soil stabilization, geosynthetics, and rehabilitation techniques that can be implemented in the short and long term.
