Description
This lecture covers the AE effect in magnetostrictive materials, focusing on the variation of Young's modulus under magnetic fields. It also discusses transducer applications, such as Terfenol and Galfenols, for smart magnetostrictive metal usage in deep-sea measurements. The presentation delves into the historical development of magnetostrictive materials, including the discovery of Terfenol-D and Galfenol. Additionally, it explores the electronic article surveillance (EAS) device, detailing the optimization strategies in materials science and engineering for effective surveillance systems.
