Abstract
This project explores magnetostrictive material, Terfenol-D, for use as an acoustic sensor. Terfenol-D was milled for 5 hours at 1000 RPM and a ball-to-powder-ratio of 10:1. Dynamic light-scattering was used to characterize particles sizes with the largest peak showing 330 nm. An increase in milling time and power can reduce the Terfenol-D particle sizes and eliminate large particle size outliers.
