The Micron School of Material Science and Engineering invites you to join us on October 23rd at 3:00 pm in MCMR 105 for Joy Morin’s dissertation defense!
Joy’s research focuses on developing a comprehensive additive manufacturing process for magnetostrictive Terfenol-D while minimizing material oxidization and understanding how printed Terfenol-D behaves under neutron radiation. Magnetostrictive terbium–iron–dysprosium alloys, commonly known as Terfenol-D, enable the generation and detection of various acoustic waveforms for structural health monitoring because of their ability to deform in response to magnetic fields and exhibit changes in magnetization under mechanical stress. However, Terfenol-D is susceptible to oxidation during manufacturing, creating challenges for its integration into acoustic transducers. Joy’s work demonstrates a MEX-based route for fabricating magnetostrictive thin films, expands the additive manufacturing material library, and provides insights into oxidation behavior and strategies for mitigating oxidation during Terfenol-D processing.
