Terfenol-D Magnetostrictive Iron Alloy (Tb0.3Dy0.7Fe1. 92)
Subcategory: Superalloy; Electronic/Magnetic Alloy; Iron Base
Key Words: T-D, Tb0.3Dy0.7Fe1. 92, magnetostrictive, giant magnetostriction, terbium, dysprosium, magnetoelastic
Material Notes: Terfenol-D is the commercial name for Tb0.3Dy0.7Fe1.92; a composition of material that exhibits giant magnetostriction. Magnetostriction is the phenomenon in which an applied magnetic field causes an anisotropic change in length in the material (Joule effect) or a change in the stress state of the material changes its magnetic properties (Villari effect). Magnetostrictive alloys have a wide range of applications in the areas of ultrasonics, sensors, audio, and transducers such as: - Actuators
- Seismic tools
- Non-round machining
- High-powered ultrasonics
- Sonar
- Fuel injection
- Vibration control
