Advanced Non-Destructive Materials Characterization
Non-destructive tools have been used for decades for detection of cracks, defects, voids, material wastage, etc. Demanding integrity problems, such as hydrogen, material aging, higher-strength materials, and materials with complex engineered structures, require new solutions. These same non-destructive tools currently used can be taken a step further to be utilized for materials characterization before significant cracks and defects arise. Electronic, magnetic, and elastic measurement combinations offer varied insights into material properties, and practices for their selection need to be developed for the appropriate applications. This advanced integration of physical phenomena measurements will result in new opportunities for the non-destructive community and the development of new analytical measurement equipment and practices. For example, these novel electronic tools are being expanded to meet the needs of our industry’s demands for pipeline integrity by relating quantitative hydrogen content measurements to physical properties. The use of advanced non-destructive measurement schemes for materials characterization, specifically hydrogen, will be discussed.
Dr. Angelique Lasseigne is a National Research Council Post-Doctorate Fellow at the National Institute of Standards and Technology in Boulder, Colorado. Angelique acts as a metallurgical engineer in the Materials Reliability Division where the focus of her research is the development of advanced non-destructive measurement schemes for material characterization. Angelique received her masters and doctorate degrees in Metallurgical Engineering from the Colorado School of Mines where she also served as Research Faculty and now Adjunct Faculty. Angelique has received awards from for research from the National Science Foundation, the American Society of Non-Destructive Testing, the International Institute of Welding, and the National Research Council.
