The purposes of this study is the development of fine fiber and ribbon sensor/actuator material elements by using the originally designed rapid solidification apparatus, and the controlling microstructures of these for application as new multi-functional materials. The functional characteristics of thermoelastic, ferromagnetic shape memory alloys and magnetoelastic alloys were improved very much, which might originate from the textures having stronger crystal anisotropy and low energy grain boundaries. These sensor/actuator material elements become useful to develop intelligent/smart material systems.
