Witryna22 mar 2024 · Terfenol-D, an alloy of TbxDy1-xFe2 (x~0.3), is a magnetostrictive material. It was originally developed by the US Naval Ordnance Laboratory in the 1970s. The technology to efficiently manufacture materials was developed in the Ames laboratory in the 1980s under the US Navy funding program. WitrynaAs a pure metal it is little used, because it reacts readily with water and air. Dysprosium’s main use is in alloys for neodymium-based magnets. This is because it is resistant to demagnetisation at high temperatures. This property is important for magnets used in motors or generators.
Witryna14 wrz 2013 · It was also suggested that terbium is a weak anti- ferromagnet (of an unknown type) between ˘218 and 230 K. The AFM state vanishes in magnetic fields exceeding 200 Oe, being replaced by the ferromagnetic (FM) state. Below 218 K, Tb was reported to be a ferromagnet.
As a component of Terfenol-D (an alloy that expands and contracts when exposed to magnetic fields more than any other alloy), terbium is of use in actuators, in naval sonar systems and in sensors . Most of the world's terbium supply is used in green phosphors. Zobacz więcej Terbium is a chemical element with the symbol Tb and atomic number 65. It is a silvery-white, rare earth metal that is malleable, and ductile.
