Serrated Yielding in Ni Superalloys

amyclarke@mines.edu
This project investigates a fundamental deformation mechanism of Ni alloys used for advance high-temperature aerospace propulsion applications. Serrated yielding results in some amount of strain that occurs at a given stress level, which may then result in dimensional change during service, which can be catastrophic. Using mechanical testing and advanced characterization techniques, the student will uncover the root causes of this phenomenon.

Student Preparation
Qualifications
The student should be interested in materials science and advanced materials. Experience with metallographic preparation and electron microscopy would be beneficial, but is not necessary.
TIME COMMITMENT (HRS/WK)
4-5
SKILLS/TECHNIQUES GAINED
This project will provide a student the opportunity to develop several skills that will be useful for graduate school or a career in the field of physical and/or mechanical metallurgy. The student will gain experience in literature review, mechanical testing, metallographic surface preparation, and microstructure characterization (SEM and EBSD).
MENTORING PLAN
The faculty mentor will meet regularly with the student, and in addition, the student will interact with graduate students and faculty in CANFSA on a weekly basis. Realistic goals will be set at the beginning of the project, and they will be continuously updated as needed. The frequent interaction with professors and graduate students will ensure all resources are being provided to ensure the student gets the most out of the project.
