Abstract
A Magnetically Activated Shape Memory Actuator (MASMA) is propiOsed. The MASMA c state-of-the-art materials technology with magnetic activation to supply a large s elevated bandwidth, actuator. MASM alloys have shown activated strains on the o 1.3% at room temperatures, for cm sized single crystals at frequencies up to an 400 Hz! The materials have also passively shown promise at cryogenic temperature of twin boundary motion and, as such, provide interesting possibilities for spa electromechanical systems. The material composition can be tailored for a wide temperatures. In the proposed work specific MASM alloy textured polycrystals, on the order of 10 cm, will be coupled with mechanical preload and field provide to yield a practical actuator for evaluation.
