- *Abstract
-
Magnetostrictive materials convert magnetic fields into mechanical strain and vice versa. They are widely used in sensors, actuators, electrical motors and other technological devices. The materials currently used for these applications are relatively inefficient (e.g. nickel or iron-aluminum alloys) or are very expensive (e.g. Terfenol-D). To address these challenges, researchers at the University of California, Berkeley, have developed a process framework using incipient martensitic transformations to achieve useful magnetostriction in relatively inexpensive materials. Early laboratory models suggest the Berkeley materials have comparable behavior to rare earth-based counterparts, with preliminary data to suggest superior performance than both rare earth-based and rare earth-free materials on the market today.
