Development of new shape memory actuator materials and their applications for smart material systems

抄録

Electro-magnetic melt-spinning method is applied for developing higher performance shape memory actuator/sensor materials. The obtained characteristic metallurgical microstructure is discussed from crystal anisotropy and grain boundary interface morphology. Our recent developments of new types of shape memory alloys of rapid-solidified TiNi systems having the capabilities of larger and faster actuation and magnetically induced ferromagnetic shape memory actuator Fe-Pd alloy system are introduced. The several potential applications by unique features of SMAS are also proposed.
