Laura Carroll, Ph.D.

Senior Staff Scientist

Research Areas:
Materials Characterization

Biography:
Dr. Laura Carroll’s research interests are largely focused on structural materials for high-temperature applications, with a particular emphasis on microstructure-property relationships and high temperature creep and creep-fatigue deformation mechanisms. Laura completed her Ph.D. in Materials Science and Engineering at the University of Michigan, where she investigated the complex high temperature creep behavior of single crystal ruthenium-containing nickel-base alloys. After her thesis studies, Laura joined General Electric Aviation where she led several programs advancing the development of high temperature turbine alloys. Now a Senior Staff Scientist at Idaho National Laboratory (INL), Laura’s focus continues to be on structural materials for demanding environments. Her main areas of focus include the analysis and characterization of the creep-fatigue behavior and underlying deformation mechanisms of a nickel-base solid solution alloy in order to facilitate qualification and use in advanced high temperature nuclear reactor designs. She is also engaged in the study of creep-fatigue behavior in advanced austenitic alloys for nuclear energy structural applications. Other areas of interest include the fundamental aspects of hydride nucleation and growth in zirconium along with long term stability strategies for precipitate strengthening in advanced gamma-gamma prime superalloys. Laura is also a key reader for Metallurgical and Materials Transactions A, has been involved in multiple round robins with ASTM International, and has over twenty peer-reviewed publications.
